The SOFA + software libraries are a collection of subprograms, in source- + code form, which implement official IAU algorithms for fundamental- + astronomy computations. The subprograms at present comprise 192 + "astronomy" routines supported by 55 "vector/matrix" routines, + available in both Fortran77 and C implementations. + + +THE SOFA INITIATIVE + +SOFA is an IAU Service which operates as a Standing Working Group under +Division A (Fundamental Astronomy). + +The IAU set up the SOFA initiative at the 1994 General Assembly, to +promulgate an authoritative set of fundamental-astronomy constants and +algorithms. At the subsequent General Assembly, in 1997, the +appointment of a review board and the selection of a site for the SOFA +Center (the outlet for SOFA products) were announced. + +The SOFA initiative was originally proposed by the IAU Working Group on +Astronomical Standards (WGAS), under the chairmanship of +Toshio Fukushima. The proposal was for "...new arrangements to +establish and maintain an accessible and authoritative set of constants, +algorithms and procedures that implement standard models used in +fundamental astronomy". The SOFA Software Libraries implement the +"algorithms" part of the SOFA initiative. They were developed under the +supervision of an international panel called the SOFA Board. The +current membership of this panel is listed in an appendix. + +A feature of the original SOFA software proposals was that the products +would be self-contained and not depend on other software. This includes +basic documentation, which, like the present file, will mostly be plain +ASCII text. It should also be noted that there is no assumption that +the software will be used on a particular computer and Operating System. +Although OS-related facilities may be present (Unix make files for +instance, use by the SOFA Center of automatic code management systems, +HTML versions of some documentation), the routines themselves will be +visible as individual text files and will run on a variety of platforms. + + +ALGORITHMS + +The SOFA Board's initial goal has been to create a set of callable +subprograms. Whether "subroutines" or "functions", they are all +referred to simply as "routines". They are designed for use by software +developers wishing to write complete applications; no runnable, free- +standing applications are included in SOFA's present plans. + +The algorithms are drawn from a variety of sources. Because most of the +routines so far developed have either been standard "text-book" +operations or implement well-documented standard algorithms, it has not +been necessary to invite the whole community to submit algorithms, +though consultation with authorities has occurred where necessary. It +should also be noted that consistency with the conventions published by +the International Earth Rotation Service was a stipulation in the +original SOFA proposals, further constraining the software designs. +This state of affairs will continue to exist for some time, as there is +a large backlog of agreed extensions to work on. However, in the future +the Board may decide to call for proposals, and is in the meantime +willing to look into any suggestions that are received by the SOFA +Center. + + +SCOPE + +The routines currently available are listed in the next two chapters of +this document. + +The "astronomy" library comprises 192 routines (plus one obsolete +Fortran routine that now appears under a revised name). The areas +addressed include calendars, astrometry, time scales, Earth rotation, +ephemerides, precession-nutation, star catalog transformations, +gnomonic projection, horizon/equatorial transformations and +geodetic/geocentric transformations. + +The "vector-matrix" library, comprising 55 routines, contains a +collection of simple tools for manipulating the vectors, matrices and +angles used by the astronomy routines. + +There is no explicit commitment by SOFA to support historical models, +though as time goes on a legacy of superseded models will naturally +accumulate. There is, for example, no support of pre-1976 precession +models, though these capabilities could be added were there significant +demand. + +Though the SOFA software libraries are rather limited in scope, and are +likely to remain so for a considerable time, they do offer distinct +advantages to prospective users. In particular, the routines are: + + * authoritative: they are IAU-backed and have been constructed with + great care; + + * practical: they are straightforward to use in spite of being + precise and rigorous (to some stated degree); + + * accessible and supported: they are downloadable from an easy-to- + find place, they are in an integrated and consistent form, they + come with adequate internal documentation, and help for users is + available. + + +VERSIONS + +Once it has been published, an issue is never revised or updated, and +remains accessible indefinitely. Subsequent issues may, however, +include corrected versions under the original routine name and +filenames. However, where a different model is introduced, it will have +a different name. + +The issues will be referred to by the date when they were announced. +The frequency of re-issue will be decided by the Board, taking into +account the importance of the changes and the impact on the user +community. + + +DOCUMENTATION + +At present there is little free-standing documentation about individual +routines. However, each routine has preamble comments which specify in +detail what the routine does and how it is used. + +The files sofa_pn_f.pdf and sofa_pn_c.pdf (for Fortran and C users +respectively) describe the SOFA tools for precession-nutation +and other aspects of Earth attitude, and include example code and, +in an appendix, diagrams showing the interrelationships between the +routines supporting the latest (IAU 2006/2000A) models. Two other pairs +of documents introduce time scale transformations (sofa_ts_f.pdf and +sofa_ts_c.pdf ) and astrometric transformations (sofa_ast_f.pdf and +sofa_ast_c.pdf).

The SOFA + software libraries are a collection of subprograms, in source- + code form, which implement official IAU algorithms for fundamental- + astronomy computations. The subprograms at present comprise 192 + "astronomy" routines supported by 55 "vector/matrix" routines, + available in both Fortran77 and C implementations. + + +THE SOFA INITIATIVE + +SOFA is an IAU Service which operates as a Standing Working Group under +Division A (Fundamental Astronomy). + +The IAU set up the SOFA initiative at the 1994 General Assembly, to +promulgate an authoritative set of fundamental-astronomy constants and +algorithms. At the subsequent General Assembly, in 1997, the +appointment of a review board and the selection of a site for the SOFA +Center (the outlet for SOFA products) were announced. + +The SOFA initiative was originally proposed by the IAU Working Group on +Astronomical Standards (WGAS), under the chairmanship of +Toshio Fukushima. The proposal was for "...new arrangements to +establish and maintain an accessible and authoritative set of constants, +algorithms and procedures that implement standard models used in +fundamental astronomy". The SOFA Software Libraries implement the +"algorithms" part of the SOFA initiative. They were developed under the +supervision of an international panel called the SOFA Board. The +current membership of this panel is listed in an appendix. + +A feature of the original SOFA software proposals was that the products +would be self-contained and not depend on other software. This includes +basic documentation, which, like the present file, will mostly be plain +ASCII text. It should also be noted that there is no assumption that +the software will be used on a particular computer and Operating System. +Although OS-related facilities may be present (Unix make files for +instance, use by the SOFA Center of automatic code management systems, +HTML versions of some documentation), the routines themselves will be +visible as individual text files and will run on a variety of platforms. + + +ALGORITHMS + +The SOFA Board's initial goal has been to create a set of callable +subprograms. Whether "subroutines" or "functions", they are all +referred to simply as "routines". They are designed for use by software +developers wishing to write complete applications; no runnable, free- +standing applications are included in SOFA's present plans. + +The algorithms are drawn from a variety of sources. Because most of the +routines so far developed have either been standard "text-book" +operations or implement well-documented standard algorithms, it has not +been necessary to invite the whole community to submit algorithms, +though consultation with authorities has occurred where necessary. It +should also be noted that consistency with the conventions published by +the International Earth Rotation Service was a stipulation in the +original SOFA proposals, further constraining the software designs. +This state of affairs will continue to exist for some time, as there is +a large backlog of agreed extensions to work on. However, in the future +the Board may decide to call for proposals, and is in the meantime +willing to look into any suggestions that are received by the SOFA +Center. + + +SCOPE + +The routines currently available are listed in the next two chapters of +this document. + +The "astronomy" library comprises 192 routines (plus one obsolete +Fortran routine that now appears under a revised name). The areas +addressed include calendars, astrometry, time scales, Earth rotation, +ephemerides, precession-nutation, star catalog transformations, +gnomonic projection, horizon/equatorial transformations and +geodetic/geocentric transformations. + +The "vector-matrix" library, comprising 55 routines, contains a +collection of simple tools for manipulating the vectors, matrices and +angles used by the astronomy routines. + +There is no explicit commitment by SOFA to support historical models, +though as time goes on a legacy of superseded models will naturally +accumulate. There is, for example, no support of pre-1976 precession +models, though these capabilities could be added were there significant +demand. + +Though the SOFA software libraries are rather limited in scope, and are +likely to remain so for a considerable time, they do offer distinct +advantages to prospective users. In particular, the routines are: + + * authoritative: they are IAU-backed and have been constructed with + great care; + + * practical: they are straightforward to use in spite of being + precise and rigorous (to some stated degree); + + * accessible and supported: they are downloadable from an easy-to- + find place, they are in an integrated and consistent form, they + come with adequate internal documentation, and help for users is + available. + + +VERSIONS + +Once it has been published, an issue is never revised or updated, and +remains accessible indefinitely. Subsequent issues may, however, +include corrected versions under the original routine name and +filenames. However, where a different model is introduced, it will have +a different name. + +The issues will be referred to by the date when they were announced. +The frequency of re-issue will be decided by the Board, taking into +account the importance of the changes and the impact on the user +community. + + +DOCUMENTATION + +At present there is little free-standing documentation about individual +routines. However, each routine has preamble comments which specify in +detail what the routine does and how it is used. + +The files sofa_pn_f.pdf and sofa_pn_c.pdf (for Fortran and C users +respectively) describe the SOFA tools for precession-nutation +and other aspects of Earth attitude, and include example code and, +in an appendix, diagrams showing the interrelationships between the +routines supporting the latest (IAU 2006/2000A) models. Two other pairs +of documents introduce time scale transformations (sofa_ts_f.pdf and +sofa_ts_c.pdf ) and astrometric transformations (sofa_ast_f.pdf and +sofa_ast_c.pdf).

Their +general appearance and coding style conforms to conventions agreed by +the SOFA Board, and their functions, names and algorithms have been +ratified by the Board. Procedures for soliciting and agreeing additions +to the library are still evolving. + + +PROGRAMMING LANGUAGES + +The SOFA routines are available in two programming languages at present: +Fortran 77 and ANSI C. + +Except for a single obsolete Fortran routine, which has no C equivalent, +there is a one-to-one relationship between the two language versions. +The naming convention is such that a SOFA routine referred to +generically as "EXAMPL" exists as a Fortran subprogram iau_EXAMPL and a +C function iauExampl. The calls for the two versions are very similar, +with the same arguments in the same order. In a few cases, the C +equivalent of a Fortran SUBROUTINE subprogram uses a return value rather +than an argument. + + +GENERAL PRINCIPLES + +The principal function of the SOFA Astronomy Library is to provide +definitive algorithms. A secondary function is to provide software +suitable for convenient direct use by writers of astronomical +applications. + +The astronomy routines call on the SOFA vector/matrix library routines, +which are separately listed, and described in sofa_vm_f.pdf (Fortran) +and sofa_vm_c.pdf (C). + +The routines are designed to exploit the full floating-point accuracy +of the machines on which they run, and not to rely on compiler +optimizations. Within these constraints, the intention is that the code +corresponds to the published formulation (if any). + +Dates are always Julian Dates (except in calendar conversion routines) +and are expressed as two double precision numbers which sum to the +required value. + +A distinction is made between routines that implement IAU-approved +models and those that use those models to create other results. The +former are referred to as "canonical models" in the preamble comments; +the latter are described as "support routines". + +Using the library requires knowledge of positional astronomy and +time-scales. These topics are covered in "Explanatory Supplement to the +Astronomical Almanac", 3rd Edition, Sean E. Urban & +P. Kenneth Seidelmann (eds.), University Science Books, 2013. Recent +developments are documented in the scientific journals, and references +to the relevant papers are given in the SOFA code as required. The IERS +Conventions are also an essential reference. The routines concerned +with Earth attitude (precession-nutation etc.) are described in the SOFA +document sofa_pn.pdf. Those concerned with transformations between +different time scales are described in sofa_ts_f.pdf (Fortran) and +sofa_ts_c.pdf (C). Those concerned with astrometric transformations +are described in sofa_ast_f.pdf (Fortran) and sofa_ast_c (C). + + +ROUTINES + + Calendars + + CAL2JD Gregorian calendar to Julian Day number + EPB

September 9 + + -------------------------- + SOFA Vector/Matrix Library + -------------------------- + +PREFACE + +The routines described here comprise the SOFA vector/matrix library. +Their general appearance and coding style conforms to conventions +agreed by the SOFA Board, and their functions, names and algorithms have +been ratified by the Board. Procedures for soliciting and agreeing +additions to the library are still evolving. + + +PROGRAMMING LANGUAGES + +The SOFA routines are available in two programming languages at present: +Fortran 77 and ANSI C. + +There is a one-to-one relationship between the two language versions. +The naming convention is such that a SOFA routine referred to +generically as "EXAMPL" exists as a Fortran subprogram iau_EXAMPL and a +C function iauExampl. The calls for the two versions are very similar, +with the same arguments in the same order. In a few cases, the C +equivalent of a Fortran SUBROUTINE subprogram uses a return value rather +than an argument. + + +GENERAL PRINCIPLES + +The library consists mostly of routines which operate on ordinary +Cartesian vectors (x,y,z) and 3x3 rotation matrices. However, there is +also support for vectors which represent velocity as well as position +and vectors which represent rotation instead of position. The vectors +which represent both position and velocity may be considered still to +have dimensions (3), but to comprise elements each of which is two +numbers, representing the value itself and the time derivative. Thus: + +* "Position" or "p" vectors (or just plain 3-vectors) have dimension + (3) in Fortran and [3] in C. + +* "Position/velocity" or "pv" vectors have dimensions (3,2) in Fortran + and [2][3] in C. + +* "Rotation" or "r" matrices have dimensions (3,3) in Fortran and [3][3] + in C. When used for rotation, they are "orthogonal"; the inverse of + such a matrix is equal to the transpose. Most of the routines in + this library do not assume that r-matrices are necessarily orthogonal + and in fact work on any 3x3 matrix. + +* "Rotation" or "r" vectors have dimensions (3) in Fortran and [3] in C. + Such vectors are a combination of the Euler axis and angle and are + convertible to and from r-matrices. The direction is the axis of + rotation and the magnitude is the angle of rotation, in radians. + Because the amount of rotation can be scaled up and down simply by + multiplying the vector by a scalar, r-vectors are useful for + representing spins about an axis which is fixed. + +* The above rules mean that in terms of memory address, the three + velocity components of a pv-vector follow the three position + components. Application code is permitted to exploit this and all + other knowledge of the internal layouts: that x, y and z appear in + that order and are in a right-handed Cartesian coordinate system etc. + For example, the cp function (copy a p-vector) can be used to copy + the velocity component of a pv-vector (indeed, this is how the + CPV routine is coded). + +* The routines provided do not completely fill the range of operations + that link all the various vector and matrix options, but are confined + to functions that are required by other parts of the SOFA software or + which are likely to prove useful. + +In addition to the vector/matrix routines, the library contains some +routines related to spherical angles, including conversions to and +from sexagesimal format. + +Using the library requires knowledge of vector/matrix methods, spherical +trigonometry, and methods of attitude representation. These topics are +covered in many textbooks, including "Spacecraft Attitude Determination +and Control", James R. Wertz (ed.), Astrophysics and Space Science +Library, Vol. 73, D.

The convention in the +** present function is that the JD day represents UTC days whether +** the length is 86399, 86400 or 86401 SI seconds. +** +** Applications should use the function iauDtf2d to convert from +** calendar date and time of day into 2-part quasi Julian Date, as +** it implements the leap-second-ambiguity convention just +** described. +** +** 4) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the +** future to be trusted. See iauDat for further details. +** +** 5) UT1-UTC is tabulated in IERS bulletins.

This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 6) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 7) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many +** applications, xp and yp can be set to zero. +** +** 8) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), +** is available, an adequate estimate of hm can be obtained from +** the expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 9) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 10) The accuracy of the result is limited by the corrections for +** refraction, which use a simple A*tan(z) + B*tan^3(z) model. +** Providing the meteorological parameters are known accurately and +** there are no gross local effects, the predicted observed +** coordinates should be within 0.05 arcsec (optical) or 1 arcsec +** (radio) for a zenith distance of less than 70 degrees, better +** than 30 arcsec (optical or radio) at 85 degrees and better +** than 20 arcmin (optical) or 30 arcmin (radio) at the horizon. +** +** Without refraction, the complementary functions iauAtco13 and +** iauAtoc13 are self-consistent to better than 1 microarcsecond +** all over the celestial sphere. With refraction included, +** consistency falls off at high zenith distances, but is still +** better than 0.05 arcsec at 85 degrees. +** +** 11) "Observed" Az,ZD means the position that would be seen by a +** perfect geodetically aligned theodolite. (Zenith distance is +** used rather than altitude in order to reflect the fact that no +** allowance is made for depression of the horizon.) This is +** related to the observed HA,Dec via the standard rotation, using +** the geodetic latitude (corrected for polar motion), while the +** observed HA and RA are related simply through the Earth rotation +** angle and the site longitude. "Observed" RA,Dec or HA,Dec thus +** means the position that would be seen by a perfect equatorial +** with its polar axis aligned to the Earth's axis of rotation. +** +** 12) It is advisable to take great care with units, as even unlikely +** values of the input parameters are accepted and processed in +** accordance with the models used. +** +** Called: +** iauApco13 astrometry parameters, ICRS-observed, 2013 +** iauAtciq quick ICRS to CIRS +** iauAtioq quick CIRS to observed +** +*/ + + + +void iauAtic13(double ri, double di, double date1, double date2, + double *rc, double *dc, double *eo) +/* +** - - - - - - - - - - +** i a u A t i c 1 3 +** - - - - - - - - - - +** +** Transform star RA,Dec from geocentric CIRS to ICRS astrometric. +** +** This function is part of the International Astronomical Union's +** SOFA (Standards of Fundamental Astronomy) software collection. +** +** Status: support function. +** +** Given: +** ri,di double CIRS geocentric RA,Dec (radians) +** date1 double TDB as a 2-part... +** date2 double ...Julian Date (Note 1) +** +** Returned: +** rc,dc double ICRS astrometric RA,Dec (radians) +** eo double equation of the origins (ERA-GST, radians, Note 4) +** +** Notes: +** +** 1) The TDB date date1+date2 is a Julian Date, apportioned in any +** convenient way between the two arguments. For example, +** JD(TDB)=2450123.7 could be expressed in any of these ways, among +** others: +** +** date1 date2 +** +** 2450123.7 0.0 (JD method) +** 2451545.0 -1421.3 (J2000 method) +** 2400000.5 50123.2 (MJD method) +** 2450123.5 0.2 (date & time method) +** +** The JD method is the most natural and convenient to use in cases +** where the loss of several decimal digits of resolution is +** acceptable. The J2000 method is best matched to the way the +** argument is handled internally and will deliver the optimum +** resolution. The MJD method and the date & time methods are both +** good compromises between resolution and convenience. For most +** applications of this function the choice will not be at all +** critical. +** +** TT can be used instead of TDB without any significant impact on +** accuracy. +** +** 2) Iterative techniques are used for the aberration and light +** deflection corrections so that the functions iauAtic13 (or +** iauAticq) and iauAtci13 (or iauAtciq) are accurate inverses; +** even at the edge of the Sun's disk the discrepancy is only about +** 1 nanoarcsecond. +** +** 3) The available accuracy is better than 1 milliarcsecond, limited +** mainly by the precession-nutation model that is used, namely +** IAU 2000A/2006. Very close to solar system bodies, additional +** errors of up to several milliarcseconds can occur because of +** unmodeled light deflection; however, the Sun's contribution is +** taken into account, to first order. The accuracy limitations of +** the SOFA function iauEpv00 (used to compute Earth position and +** velocity) can contribute aberration errors of up to +** 5 microarcseconds. Light deflection at the Sun's limb is +** uncertain at the 0.4 mas level. +** +** 4) Should the transformation to (equinox based) J2000.0 mean place +** be required rather than (CIO based) ICRS coordinates, subtract the +** equation of the origins from the returned right ascension: +** RA = RI - EO.

For star +** positions in the ICRS, these effects can be applied by means of +** the iauAtci13 (etc.) functions. Starting from classical "mean +** place" systems, additional transformations will be needed first. +** +** 5) "Observed" Az,El means the position that would be seen by a +** perfect geodetically aligned theodolite. This is obtained from +** the CIRS RA,Dec by allowing for Earth orientation and diurnal +** aberration, rotating from equator to horizon coordinates, and +** then adjusting for refraction.

TT is a +** specific linear transformation of geocentric coordinate time TCG, +** which is the time scale for the Geocentric Celestial Reference +** System, GCRS. +** +** 3) TDB is a coordinate time, and is a specific linear transformation +** of barycentric coordinate time TCB, which is the time scale for +** the Barycentric Celestial Reference System, BCRS. +** +** 4) The difference TCG-TCB depends on the masses and positions of the +** bodies of the solar system and the velocity of the Earth. It is +** dominated by a rate difference, the residual being of a periodic +** character. The latter, which is modeled by the present function, +** comprises a main (annual) sinusoidal term of amplitude +** approximately 0.00166 seconds, plus planetary terms up to about +** 20 microseconds, and lunar and diurnal terms up to 2 microseconds. +** These effects come from the changing transverse Doppler effect +** and gravitational red-shift as the observer (on the Earth's +** surface) experiences variations in speed (with respect to the +** BCRS) and gravitational potential. +** +** 5) TDB can be regarded as the same as TCB but with a rate adjustment +** to keep it close to TT, which is convenient for many applications. +** The history of successive attempts to define TDB is set out in +** Resolution 3 adopted by the IAU General Assembly in 2006, which +** defines a fixed TDB(TCB) transformation that is consistent with +** contemporary solar-system ephemerides. Future ephemerides will +** imply slightly changed transformations between TCG and TCB, which +** could introduce a linear drift between TDB and TT; however, any +** such drift is unlikely to exceed 1 nanosecond per century. +** +** 6) The geocentric TDB-TT model used in the present function is that of +** Fairhead & Bretagnon (1990), in its full form. It was originally +** supplied by Fairhead (private communications with P.T.Wallace, +** 1990) as a Fortran subroutine. The present C function contains an +** adaptation of the Fairhead code.

The +** obliquity at J2000.0 is assumed to be the Lieske et al. (1977) +** value of 84381.448 arcsec. +** +** Both the luni-solar and planetary nutations are included. The +** latter are due to direct planetary nutations and the +** perturbations of the lunar and terrestrial orbits. +** +** 3) The function computes the MHB2000 nutation series with the +** associated corrections for planetary nutations. It is an +** implementation of the nutation part of the IAU 2000A precession- +** nutation model, formally adopted by the IAU General Assembly in +** 2000, namely MHB2000 (Mathews et al. 2002), but with the free +** core nutation (FCN - see Note 4) omitted. +** +** 4) The full MHB2000 model also contains contributions to the +** nutations in longitude and obliquity due to the free-excitation +** of the free-core-nutation during the period 1979-2000. These FCN +** terms, which are time-dependent and unpredictable, are NOT +** included in the present function and, if required, must be +** independently computed. With the FCN corrections included, the +** present function delivers a pole which is at current epochs +** accurate to a few hundred microarcseconds. The omission of FCN +** introduces further errors of about that size. +** +** 5) The present function provides classical nutation. The MHB2000 +** algorithm, from which it is adapted, deals also with (i) the +** offsets between the GCRS and mean poles and (ii) the adjustments +** in longitude and obliquity due to the changed precession rates. +** These additional functions, namely frame bias and precession +** adjustments, are supported by the SOFA functions iauBi00 and +** iauPr00. +** +** 6) The MHB2000 algorithm also provides "total" nutations, comprising +** the arithmetic sum of the frame bias, precession adjustments, +** luni-solar nutation and planetary nutation. These total +** nutations can be used in combination with an existing IAU 1976 +** precession implementation, such as iauPmat76, to deliver GCRS- +** to-true predictions of sub-mas accuracy at current dates. +** However, there are three shortcomings in the MHB2000 model that +** must be taken into account if more accurate or definitive results +** are required (see Wallace 2002): +** +** (i) The MHB2000 total nutations are simply arithmetic sums, +** yet in reality the various components are successive Euler +** rotations. This slight lack of rigor leads to cross terms +** that exceed 1 mas after a century. The rigorous procedure +** is to form the GCRS-to-true rotation matrix by applying the +** bias, precession and nutation in that order. +** +** (ii) Although the precession adjustments are stated to be with +** respect to Lieske et al. (1977), the MHB2000 model does +** not specify which set of Euler angles are to be used and +** how the adjustments are to be applied. The most literal +** and straightforward procedure is to adopt the 4-rotation +** epsilon_0, psi_A, omega_A, xi_A option, and to add DPSIPR +** to psi_A and DEPSPR to both omega_A and eps_A. +** +** (iii) The MHB2000 model predates the determination by Chapront +** et al.

The +** obliquity at J2000.0 is assumed to be the Lieske et al. (1977) +** value of 84381.448 arcsec. (The errors that result from using +** this function with the IAU 2006 value of 84381.406 arcsec can be +** neglected.) +** +** The nutation model consists only of luni-solar terms, but +** includes also a fixed offset which compensates for certain long- +** period planetary terms (Note 7). +** +** 3) This function is an implementation of the IAU 2000B abridged +** nutation model formally adopted by the IAU General Assembly in +** 2000. The function computes the MHB_2000_SHORT luni-solar +** nutation series (Luzum 2001), but without the associated +** corrections for the precession rate adjustments and the offset +** between the GCRS and J2000.0 mean poles. +** +** 4) The full IAU 2000A (MHB2000) nutation model contains nearly 1400 +** terms. The IAU 2000B model (McCarthy & Luzum 2003) contains only +** 77 terms, plus additional simplifications, yet still delivers +** results of 1 mas accuracy at present epochs. This combination of +** accuracy and size makes the IAU 2000B abridged nutation model +** suitable for most practical applications. +** +** The function delivers a pole accurate to 1 mas from 1900 to 2100 +** (usually better than 1 mas, very occasionally just outside +** 1 mas). The full IAU 2000A model, which is implemented in the +** function iauNut00a (q.v.), delivers considerably greater accuracy +** at current dates; however, to realize this improved accuracy, +** corrections for the essentially unpredictable free-core-nutation +** (FCN) must also be included. +** +** 5) The present function provides classical nutation. The +** MHB_2000_SHORT algorithm, from which it is adapted, deals also +** with (i) the offsets between the GCRS and mean poles and (ii) the +** adjustments in longitude and obliquity due to the changed +** precession rates. These additional functions, namely frame bias +** and precession adjustments, are supported by the SOFA functions +** iauBi00 and iauPr00. +** +** 6) The MHB_2000_SHORT algorithm also provides "total" nutations, +** comprising the arithmetic sum of the frame bias, precession +** adjustments, and nutation (luni-solar + planetary). These total +** nutations can be used in combination with an existing IAU 1976 +** precession implementation, such as iauPmat76, to deliver GCRS- +** to-true predictions of mas accuracy at current epochs. However, +** for symmetry with the iauNut00a function (q.v. for the reasons), +** the SOFA functions do not generate the "total nutations" +** directly. Should they be required, they could of course easily +** be generated by calling iauBi00, iauPr00 and the present function +** and adding the results. +** +** 7) The IAU 2000B model includes "planetary bias" terms that are +** fixed in size but compensate for long-period nutations. The +** amplitudes quoted in McCarthy & Luzum (2003), namely +** Dpsi = -1.5835 mas and Depsilon = +1.6339 mas, are optimized for +** the "total nutations" method described in Note 6. The Luzum +** (2001) values used in this SOFA implementation, namely -0.135 mas +** and +0.388 mas, are optimized for the "rigorous" method, where +** frame bias, precession and nutation are applied separately and in +** that order. During the interval 1995-2050, the SOFA +** implementation delivers a maximum error of 1.001 mas (not +** including FCN). +** +** References: +** +** Lieske, J.H., Lederle, T., Fricke, W., Morando, B., "Expressions +** for the precession quantities based upon the IAU /1976/ system of +** astronomical constants", Astron.Astrophys. 58, 1-2, 1-16.

For most practical applications, it is +** permissible to neglect the distinction between TCB and ordinary +** "proper" time on Earth (TT/TAI). The result will, as a rule, be +** limited by the intrinsic accuracy of the proper-motion and +** radial-velocity data; moreover, the pv-vector is likely to be +** merely an intermediate result, so that a change of time unit +** would cancel out overall. +** +** In accordance with normal star-catalog conventions, the object's +** right ascension and declination are freed from the effects of +** secular aberration. The frame, which is aligned to the catalog +** equator and equinox, is Lorentzian and centered on the SSB. +** +** 2) The resulting position and velocity pv-vector is with respect to +** the same frame and, like the catalog coordinates, is freed from +** the effects of secular aberration. Should the "coordinate +** direction", where the object was located at the catalog epoch, be +** required, it may be obtained by calculating the magnitude of the +** position vector pv[0][0-2] dividing by the speed of light in +** au/day to give the light-time, and then multiplying the space +** velocity pv[1][0-2] by this light-time and adding the result to +** pv[0][0-2]. +** +** Summarizing, the pv-vector returned is for most stars almost +** identical to the result of applying the standard geometrical +** "space motion" transformation. The differences, which are the +** subject of the Stumpff paper referenced below, are: +** +** (i) In stars with significant radial velocity and proper motion, +** the constantly changing light-time distorts the apparent proper +** motion. Note that this is a classical, not a relativistic, +** effect. +** +** (ii) The transformation complies with special relativity. +** +** 3) Care is needed with units. The star coordinates are in radians +** and the proper motions in radians per Julian year, but the +** parallax is in arcseconds; the radial velocity is in km/s, but +** the pv-vector result is in au and au/day. +** +** 4) The RA proper motion is in terms of coordinate angle, not true +** angle.

Their +general appearance and coding style conforms to conventions agreed by +the SOFA Board, and their functions, names and algorithms have been +ratified by the Board. Procedures for soliciting and agreeing additions +to the library are still evolving. + + +PROGRAMMING LANGUAGES + +The SOFA routines are available in two programming languages at present: +Fortran 77 and ANSI C. + +Except for a single obsolete Fortran routine, which has no C equivalent, +there is a one-to-one relationship between the two language versions. +The naming convention is such that a SOFA routine referred to +generically as "EXAMPL" exists as a Fortran subprogram iau_EXAMPL and a +C function iauExampl. The calls for the two versions are very similar, +with the same arguments in the same order. In a few cases, the C +equivalent of a Fortran SUBROUTINE subprogram uses a return value rather +than an argument. + + +GENERAL PRINCIPLES + +The principal function of the SOFA Astronomy Library is to provide +definitive algorithms. A secondary function is to provide software +suitable for convenient direct use by writers of astronomical +applications. + +The astronomy routines call on the SOFA vector/matrix library routines, +which are separately listed, and described in sofa_vm_f.pdf (Fortran) +and sofa_vm_c.pdf (C). + +The routines are designed to exploit the full floating-point accuracy +of the machines on which they run, and not to rely on compiler +optimizations. Within these constraints, the intention is that the code +corresponds to the published formulation (if any). + +Dates are always Julian Dates (except in calendar conversion routines) +and are expressed as two double precision numbers which sum to the +required value. + +A distinction is made between routines that implement IAU-approved +models and those that use those models to create other results. The +former are referred to as "canonical models" in the preamble comments; +the latter are described as "support routines". + +Using the library requires knowledge of positional astronomy and +time-scales. These topics are covered in "Explanatory Supplement to the +Astronomical Almanac", 3rd Edition, Sean E. Urban & +P. Kenneth Seidelmann (eds.), University Science Books, 2013. Recent +developments are documented in the scientific journals, and references +to the relevant papers are given in the SOFA code as required. The IERS +Conventions are also an essential reference. The routines concerned +with Earth attitude (precession-nutation etc.) are described in the SOFA +document sofa_pn.pdf. Those concerned with transformations between +different time scales are described in sofa_ts_f.pdf (Fortran) and +sofa_ts_c.pdf (C). Those concerned with astrometric transformations +are described in sofa_ast_f.pdf (Fortran) and sofa_ast_c (C). + + +ROUTINES + + Calendars + + CAL2JD Gregorian calendar to Julian Day number + EPB

-------------------------- + SOFA Vector/Matrix Library + -------------------------- + +PREFACE + +The routines described here comprise the SOFA vector/matrix library. +Their general appearance and coding style conforms to conventions +agreed by the SOFA Board, and their functions, names and algorithms have +been ratified by the Board. Procedures for soliciting and agreeing +additions to the library are still evolving. + + +PROGRAMMING LANGUAGES + +The SOFA routines are available in two programming languages at present: +Fortran 77 and ANSI C. + +There is a one-to-one relationship between the two language versions. +The naming convention is such that a SOFA routine referred to +generically as "EXAMPL" exists as a Fortran subprogram iau_EXAMPL and a +C function iauExampl. The calls for the two versions are very similar, +with the same arguments in the same order. In a few cases, the C +equivalent of a Fortran SUBROUTINE subprogram uses a return value rather +than an argument. + + +GENERAL PRINCIPLES + +The library consists mostly of routines which operate on ordinary +Cartesian vectors (x,y,z) and 3x3 rotation matrices. However, there is +also support for vectors which represent velocity as well as position +and vectors which represent rotation instead of position. The vectors +which represent both position and velocity may be considered still to +have dimensions (3), but to comprise elements each of which is two +numbers, representing the value itself and the time derivative. Thus: + +* "Position" or "p" vectors (or just plain 3-vectors) have dimension + (3) in Fortran and [3] in C. + +* "Position/velocity" or "pv" vectors have dimensions (3,2) in Fortran + and [2][3] in C. + +* "Rotation" or "r" matrices have dimensions (3,3) in Fortran and [3][3] + in C. When used for rotation, they are "orthogonal"; the inverse of + such a matrix is equal to the transpose. Most of the routines in + this library do not assume that r-matrices are necessarily orthogonal + and in fact work on any 3x3 matrix. + +* "Rotation" or "r" vectors have dimensions (3) in Fortran and [3] in C. + Such vectors are a combination of the Euler axis and angle and are + convertible to and from r-matrices. The direction is the axis of + rotation and the magnitude is the angle of rotation, in radians. + Because the amount of rotation can be scaled up and down simply by + multiplying the vector by a scalar, r-vectors are useful for + representing spins about an axis which is fixed. + +* The above rules mean that in terms of memory address, the three + velocity components of a pv-vector follow the three position + components. Application code is permitted to exploit this and all + other knowledge of the internal layouts: that x, y and z appear in + that order and are in a right-handed Cartesian coordinate system etc. + For example, the cp function (copy a p-vector) can be used to copy + the velocity component of a pv-vector (indeed, this is how the + CPV routine is coded). + +* The routines provided do not completely fill the range of operations + that link all the various vector and matrix options, but are confined + to functions that are required by other parts of the SOFA software or + which are likely to prove useful. + +In addition to the vector/matrix routines, the library contains some +routines related to spherical angles, including conversions to and +from sexagesimal format. + +Using the library requires knowledge of vector/matrix methods, spherical +trigonometry, and methods of attitude representation. These topics are +covered in many textbooks, including "Spacecraft Attitude Determination +and Control", James R. Wertz (ed.), Astrophysics and Space Science +Library, Vol. 73, D.

For many +** applications, xp and yp can be set to zero. +** +** Internally, the polar motion is stored in a form rotated onto +** the local meridian. +** +** 6) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), is +** available, an adequate estimate of hm can be obtained from the +** expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 7) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 8) It is advisable to take great care with units, as even unlikely +** values of the input parameters are accepted and processed in +** accordance with the models used. +** +** 9) In cases where the caller wishes to supply his own Earth +** ephemeris, Earth rotation information and refraction constants, +** the function iauApco can be used instead of the present function. +** +** 10) This is one of several functions that inserts into the astrom +** structure star-independent parameters needed for the chain of +** astrometric transformations ICRS <-> GCRS <-> CIRS <-> observed. +** +** The various functions support different classes of observer and +** portions of the transformation chain: +** +** functions observer transformation +** +** iauApcg iauApcg13 geocentric ICRS <-> GCRS +** iauApci iauApci13 terrestrial ICRS <-> CIRS +** iauApco iauApco13 terrestrial ICRS <-> observed +** iauApcs iauApcs13 space ICRS <-> GCRS +** iauAper iauAper13 terrestrial update Earth rotation +** iauApio iauApio13 terrestrial CIRS <-> observed +** +** Those with names ending in "13" use contemporary SOFA models to +** compute the various ephemerides.

The convention in the +** present function is that the JD day represents UTC days whether +** the length is 86399, 86400 or 86401 SI seconds. +** +** Applications should use the function iauDtf2d to convert from +** calendar date and time of day into 2-part quasi Julian Date, as +** it implements the leap-second-ambiguity convention just +** described. +** +** 2) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the future +** to be trusted. See iauDat for further details. +** +** 3) UT1-UTC is tabulated in IERS bulletins. It increases by exactly +** one second at the end of each positive UTC leap second, +** introduced in order to keep UT1-UTC within +/- 0.9s. n.b. This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 4) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 5) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many applications, +** xp and yp can be set to zero. +** +** Internally, the polar motion is stored in a form rotated onto +** the local meridian. +** +** 6) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), is +** available, an adequate estimate of hm can be obtained from the +** expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to the +** pressure and that an accurate phpa value is important for +** precise work. +** +** 7) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 8) It is advisable to take great care with units, as even unlikely +** values of the input parameters are accepted and processed in +** accordance with the models used. +** +** 9) In cases where the caller wishes to supply his own Earth +** rotation information and refraction constants, the function +** iauApc can be used instead of the present function. +** +** 10) This is one of several functions that inserts into the astrom +** structure star-independent parameters needed for the chain of +** astrometric transformations ICRS <-> GCRS <-> CIRS <-> observed. +** +** The various functions support different classes of observer and +** portions of the transformation chain: +** +** functions observer transformation +** +** iauApcg iauApcg13 geocentric ICRS <-> GCRS +** iauApci iauApci13 terrestrial ICRS <-> CIRS +** iauApco iauApco13 terrestrial ICRS <-> observed +** iauApcs iauApcs13 space ICRS <-> GCRS +** iauAper iauAper13 terrestrial update Earth rotation +** iauApio iauApio13 terrestrial CIRS <-> observed +** +** Those with names ending in "13" use contemporary SOFA models to +** compute the various ephemerides.

The convention in the +** present function is that the JD day represents UTC days whether +** the length is 86399, 86400 or 86401 SI seconds. +** +** Applications should use the function iauDtf2d to convert from +** calendar date and time of day into 2-part quasi Julian Date, as +** it implements the leap-second-ambiguity convention just +** described. +** +** 4) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the +** future to be trusted. See iauDat for further details. +** +** 5) UT1-UTC is tabulated in IERS bulletins. It increases by exactly +** one second at the end of each positive UTC leap second, +** introduced in order to keep UT1-UTC within +/- 0.9s. n.b. This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 6) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 7) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many +** applications, xp and yp can be set to zero. +** +** 8) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), +** is available, an adequate estimate of hm can be obtained from +** the expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 9) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 10) The accuracy of the result is limited by the corrections for +** refraction, which use a simple A*tan(z) + B*tan^3(z) model. +** Providing the meteorological parameters are known accurately and +** there are no gross local effects, the predicted observed +** coordinates should be within 0.05 arcsec (optical) or 1 arcsec +** (radio) for a zenith distance of less than 70 degrees, better +** than 30 arcsec (optical or radio) at 85 degrees and better +** than 20 arcmin (optical) or 30 arcmin (radio) at the horizon. +** +** Without refraction, the complementary functions iauAtco13 and +** iauAtoc13 are self-consistent to better than 1 microarcsecond +** all over the celestial sphere. With refraction included, +** consistency falls off at high zenith distances, but is still +** better than 0.05 arcsec at 85 degrees. +** +** 11) "Observed" Az,ZD means the position that would be seen by a +** perfect geodetically aligned theodolite. (Zenith distance is +** used rather than altitude in order to reflect the fact that no +** allowance is made for depression of the horizon.) This is +** related to the observed HA,Dec via the standard rotation, using +** the geodetic latitude (corrected for polar motion), while the +** observed HA and RA are related simply through the Earth rotation +** angle and the site longitude. "Observed" RA,Dec or HA,Dec thus +** means the position that would be seen by a perfect equatorial +** with its polar axis aligned to the Earth's axis of rotation. +** +** 12) It is advisable to take great care with units, as even unlikely +** values of the input parameters are accepted and processed in +** accordance with the models used. +** +** Called: +** iauApco13 astrometry parameters, ICRS-observed, 2013 +** iauAtciq quick ICRS to CIRS +** iauAtioq quick CIRS to observed +** +** This revision: 2022 May 3 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

See iauDat for further details. +** +** 3) UT1-UTC is tabulated in IERS bulletins. It increases by exactly +** one second at the end of each positive UTC leap second, +** introduced in order to keep UT1-UTC within +/- 0.9s. n.b. This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 4) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 5) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many +** applications, xp and yp can be set to zero. +** +** 6) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), is +** available, an adequate estimate of hm can be obtained from the +** expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 7) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 8) "Observed" Az,ZD means the position that would be seen by a +** perfect geodetically aligned theodolite. (Zenith distance is +** used rather than altitude in order to reflect the fact that no +** allowance is made for depression of the horizon.) This is +** related to the observed HA,Dec via the standard rotation, using +** the geodetic latitude (corrected for polar motion), while the +** observed HA and RA are related simply through the Earth rotation +** angle and the site longitude. "Observed" RA,Dec or HA,Dec thus +** means the position that would be seen by a perfect equatorial +** with its polar axis aligned to the Earth's axis of rotation. +** +** 9) The accuracy of the result is limited by the corrections for +** refraction, which use a simple A*tan(z) + B*tan^3(z) model. +** Providing the meteorological parameters are known accurately and +** there are no gross local effects, the predicted astrometric +** coordinates should be within 0.05 arcsec (optical) or 1 arcsec +** (radio) for a zenith distance of less than 70 degrees, better +** than 30 arcsec (optical or radio) at 85 degrees and better +** than 20 arcmin (optical) or 30 arcmin (radio) at the horizon. +** +** 10) The complementary functions iauAtio13 and iauAtoi13 are self- +** consistent to better than 1 microarcsecond all over the +** celestial sphere. +** +** 11) It is advisable to take great care with units, as even unlikely +** values of the input parameters are accepted and processed in +** accordance with the models used. +** +** Called: +** iauApio13 astrometry parameters, CIRS-observed, 2013 +** iauAtioq quick CIRS to observed +** +** This revision: 2021 February 24 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

(Zenith distance is +** used rather than altitude in order to reflect the fact that no +** allowance is made for depression of the horizon.) This is +** related to the observed HA,Dec via the standard rotation, using +** the geodetic latitude (corrected for polar motion), while the +** observed HA and (CIO-based) RA are related simply through the +** Earth rotation angle and the site longitude. "Observed" RA,Dec +** or HA,Dec thus means the position that would be seen by a +** perfect equatorial with its polar axis aligned to the Earth's +** axis of rotation. +** +** 2) Only the first character of the type argument is significant. +** "R" or "r" indicates that ob1 and ob2 are the observed right +** ascension (CIO-based) and declination; "H" or "h" indicates +** that they are hour angle (west +ve) and declination; anything +** else ("A" or "a" is recommended) indicates that ob1 and ob2 are +** azimuth (north zero, east 90 deg) and zenith distance. +** +** 3) utc1+utc2 is quasi Julian Date (see Note 2), apportioned in any +** convenient way between the two arguments, for example where utc1 +** is the Julian Day Number and utc2 is the fraction of a day. +** +** However, JD cannot unambiguously represent UTC during a leap +** second unless special measures are taken. The convention in the +** present function is that the JD day represents UTC days whether +** the length is 86399, 86400 or 86401 SI seconds. +** +** Applications should use the function iauDtf2d to convert from +** calendar date and time of day into 2-part quasi Julian Date, as +** it implements the leap-second-ambiguity convention just +** described. +** +** 4) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the +** future to be trusted. See iauDat for further details. +** +** 5) UT1-UTC is tabulated in IERS bulletins. It increases by exactly +** one second at the end of each positive UTC leap second, +** introduced in order to keep UT1-UTC within +/- 0.9s. n.b. This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 6) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 7) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many +** applications, xp and yp can be set to zero. +** +** 8) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), is +** available, an adequate estimate of hm can be obtained from the +** expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 9) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 10) The accuracy of the result is limited by the corrections for +** refraction, which use a simple A*tan(z) + B*tan^3(z) model. +** Providing the meteorological parameters are known accurately and +** there are no gross local effects, the predicted astrometric +** coordinates should be within 0.05 arcsec (optical) or 1 arcsec +** (radio) for a zenith distance of less than 70 degrees, better +** than 30 arcsec (optical or radio) at 85 degrees and better +** than 20 arcmin (optical) or 30 arcmin (radio) at the horizon. +** +** Without refraction, the complementary functions iauAtco13 and +** iauAtoc13 are self-consistent to better than 1 microarcsecond +** all over the celestial sphere.

(Zenith distance is +** used rather than altitude in order to reflect the fact that no +** allowance is made for depression of the horizon.) This is +** related to the observed HA,Dec via the standard rotation, using +** the geodetic latitude (corrected for polar motion), while the +** observed HA and (CIO-based) RA are related simply through the +** Earth rotation angle and the site longitude. "Observed" RA,Dec +** or HA,Dec thus means the position that would be seen by a +** perfect equatorial with its polar axis aligned to the Earth's +** axis of rotation. +** +** 2) Only the first character of the type argument is significant. +** "R" or "r" indicates that ob1 and ob2 are the observed right +** ascension and declination; "H" or "h" indicates that they are +** hour angle (west +ve) and declination; anything else ("A" or +** "a" is recommended) indicates that ob1 and ob2 are azimuth +** (north zero, east 90 deg) and zenith distance. +** +** 3) utc1+utc2 is quasi Julian Date (see Note 2), apportioned in any +** convenient way between the two arguments, for example where utc1 +** is the Julian Day Number and utc2 is the fraction of a day. +** +** However, JD cannot unambiguously represent UTC during a leap +** second unless special measures are taken. The convention in the +** present function is that the JD day represents UTC days whether +** the length is 86399, 86400 or 86401 SI seconds. +** +** Applications should use the function iauDtf2d to convert from +** calendar date and time of day into 2-part quasi Julian Date, as +** it implements the leap-second-ambiguity convention just +** described. +** +** 4) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the +** future to be trusted. See iauDat for further details. +** +** 5) UT1-UTC is tabulated in IERS bulletins. It increases by exactly +** one second at the end of each positive UTC leap second, +** introduced in order to keep UT1-UTC within +/- 0.9s. n.b. This +** practice is under review, and in the future UT1-UTC may grow +** essentially without limit. +** +** 6) The geographical coordinates are with respect to the WGS84 +** reference ellipsoid. TAKE CARE WITH THE LONGITUDE SIGN: the +** longitude required by the present function is east-positive +** (i.e. right-handed), in accordance with geographical convention. +** +** 7) The polar motion xp,yp can be obtained from IERS bulletins. The +** values are the coordinates (in radians) of the Celestial +** Intermediate Pole with respect to the International Terrestrial +** Reference System (see IERS Conventions 2003), measured along the +** meridians 0 and 90 deg west respectively. For many +** applications, xp and yp can be set to zero. +** +** 8) If hm, the height above the ellipsoid of the observing station +** in meters, is not known but phpa, the pressure in hPa (=mB), is +** available, an adequate estimate of hm can be obtained from the +** expression +** +** hm = -29.3 * tsl * log ( phpa / 1013.25 ); +** +** where tsl is the approximate sea-level air temperature in K +** (See Astrophysical Quantities, C.W.Allen, 3rd edition, section +** 52). Similarly, if the pressure phpa is not known, it can be +** estimated from the height of the observing station, hm, as +** follows: +** +** phpa = 1013.25 * exp ( -hm / ( 29.3 * tsl ) ); +** +** Note, however, that the refraction is nearly proportional to +** the pressure and that an accurate phpa value is important for +** precise work. +** +** 9) The argument wl specifies the observing wavelength in +** micrometers. The transition from optical to radio is assumed to +** occur at 100 micrometers (about 3000 GHz). +** +** 10) The accuracy of the result is limited by the corrections for +** refraction, which use a simple A*tan(z) + B*tan^3(z) model. +** Providing the meteorological parameters are known accurately and +** there are no gross local effects, the predicted astrometric +** coordinates should be within 0.05 arcsec (optical) or 1 arcsec +** (radio) for a zenith distance of less than 70 degrees, better +** than 30 arcsec (optical or radio) at 85 degrees and better +** than 20 arcmin (optical) or 30 arcmin (radio) at the horizon. +** +** Without refraction, the complementary functions iauAtio13 and +** iauAtoi13 are self-consistent to better than 1 microarcsecond +** all over the celestial sphere.

If this is attempted, +** zero is returned together with a warning status. +** +** Because leap seconds cannot, in principle, be predicted in +** advance, a reliable check for dates beyond the valid range is +** impossible. To guard against gross errors, a year five or more +** after the release year of the present function (see the constant +** IYV) is considered dubious. In this case a warning status is +** returned but the result is computed in the normal way. +** +** For both too-early and too-late years, the warning status is +1. +** This is distinct from the error status -1, which signifies a year +** so early that JD could not be computed. +** +** 2) If the specified date is for a day which ends with a leap second, +** the TAI-UTC value returned is for the period leading up to the +** leap second. If the date is for a day which begins as a leap +** second ends, the TAI-UTC returned is for the period following the +** leap second. +** +** 3) The day number must be in the normal calendar range, for example +** 1 through 30 for April. The "almanac" convention of allowing +** such dates as January 0 and December 32 is not supported in this +** function, in order to avoid confusion near leap seconds. +** +** 4) The fraction of day is used only for dates before the +** introduction of leap seconds, the first of which occurred at the +** end of 1971. It is tested for validity (0 to 1 is the valid +** range) even if not used; if invalid, zero is used and status -4 +** is returned. For many applications, setting fd to zero is +** acceptable; the resulting error is always less than 3 ms (and +** occurs only pre-1972). +** +** 5) The status value returned in the case where there are multiple +** errors refers to the first error detected. For example, if the +** month and day are 13 and 32 respectively, status -2 (bad month) +** will be returned. The "internal error" status refers to a +** case that is impossible but causes some compilers to issue a +** warning. +** +** 6) In cases where a valid result is not available, zero is returned. +** +** References: +** +** 1) For dates from 1961 January 1 onwards, the expressions from the +** file ftp://maia.usno.navy.mil/ser7/tai-utc.dat are used. +** +** 2) The 5ms timestep at 1961 January 1 is taken from 2.58.1 (p87) of +** the 1992 Explanatory Supplement. +** +** Called: +** iauCal2jd Gregorian calendar to JD +** +** This revision: 2023 January 17 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

The J2000 method is best matched to the way +** the argument is handled internally and will deliver the +** optimum resolution. The MJD method and the date & time methods +** are both good compromises between resolution and convenience. +** +** Although the date is, formally, barycentric dynamical time (TDB), +** the terrestrial dynamical time (TT) can be used with no practical +** effect on the accuracy of the prediction. +** +** 2) TT can be regarded as a coordinate time that is realized as an +** offset of 32.184s from International Atomic Time, TAI. TT is a +** specific linear transformation of geocentric coordinate time TCG, +** which is the time scale for the Geocentric Celestial Reference +** System, GCRS. +** +** 3) TDB is a coordinate time, and is a specific linear transformation +** of barycentric coordinate time TCB, which is the time scale for +** the Barycentric Celestial Reference System, BCRS. +** +** 4) The difference TCG-TCB depends on the masses and positions of the +** bodies of the solar system and the velocity of the Earth. It is +** dominated by a rate difference, the residual being of a periodic +** character. The latter, which is modeled by the present function, +** comprises a main (annual) sinusoidal term of amplitude +** approximately 0.00166 seconds, plus planetary terms up to about +** 20 microseconds, and lunar and diurnal terms up to 2 microseconds. +** These effects come from the changing transverse Doppler effect +** and gravitational red-shift as the observer (on the Earth's +** surface) experiences variations in speed (with respect to the +** BCRS) and gravitational potential. +** +** 5) TDB can be regarded as the same as TCB but with a rate adjustment +** to keep it close to TT, which is convenient for many applications. +** The history of successive attempts to define TDB is set out in +** Resolution 3 adopted by the IAU General Assembly in 2006, which +** defines a fixed TDB(TCB) transformation that is consistent with +** contemporary solar-system ephemerides. Future ephemerides will +** imply slightly changed transformations between TCG and TCB, which +** could introduce a linear drift between TDB and TT; however, any +** such drift is unlikely to exceed 1 nanosecond per century. +** +** 6) The geocentric TDB-TT model used in the present function is that of +** Fairhead & Bretagnon (1990), in its full form. It was originally +** supplied by Fairhead (private communications with P.T.Wallace, +** 1990) as a Fortran subroutine. The present C function contains an +** adaptation of the Fairhead code. The numerical results are +** essentially unaffected by the changes, the differences with +** respect to the Fairhead & Bretagnon original being at the 1e-20 s +** level. +** +** The topocentric part of the model is from Moyer (1981) and +** Murray (1983), with fundamental arguments adapted from +** Simon et al. 1994. It is an approximation to the expression +** ( v / c ) . ( r / c ), where v is the barycentric velocity of +** the Earth, r is the geocentric position of the observer and +** c is the speed of light. +** +** By supplying zeroes for u and v, the topocentric part of the +** model can be nullified, and the function will return the Fairhead +** & Bretagnon result alone. +** +** 7) During the interval 1950-2050, the absolute accuracy is better +** than +/- 3 nanoseconds relative to time ephemerides obtained by +** direct numerical integrations based on the JPL DE405 solar system +** ephemeris. +** +** 8) It must be stressed that the present function is merely a model, +** and that numerical integration of solar-system ephemerides is the +** definitive method for predicting the relationship between TCG and +** TCB and hence between TT and TDB. +** +** References: +** +** Fairhead, L., & Bretagnon, P., Astron.Astrophys., 229, 240-247 +** (1990). +** +** IAU 2006 Resolution 3. +** +** McCarthy, D.

The SOFA internal convention is that +** the quasi-JD day represents UTC days whether the length is 86399, +** 86400 or 86401 SI seconds. In the 1960-1972 era there were +** smaller jumps (in either direction) each time the linear UTC(TAI) +** expression was changed, and these "mini-leaps" are also included +** in the SOFA convention. +** +** 5) The warning status "time is after end of day" usually means that +** the sec argument is greater than 60.0. However, in a day ending +** in a leap second the limit changes to 61.0 (or 59.0 in the case +** of a negative leap second). +** +** 6) The warning status "dubious year" flags UTCs that predate the +** introduction of the time scale or that are too far in the future +** to be trusted. See iauDat for further details. +** +** 7) Only in the case of continuous and regular time scales (TAI, TT, +** TCG, TCB and TDB) is the result d1+d2 a Julian Date, strictly +** speaking. In the other cases (UT1 and UTC) the result must be +** used with circumspection; in particular the difference between +** two such results cannot be interpreted as a precise time +** interval. +** +** Called: +** iauCal2jd Gregorian calendar to JD +** iauDat delta(AT) = TAI-UTC +** iauJd2cal JD to Gregorian calendar +** +** This revision: 2023 May 6 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

Change of standard epoch from B1950.0 to J2000.0. +** +** . An intermediate transition date of 1984 January 1.0 TT. +** +** . A change of precession model. +** +** . Change of time unit for proper motion (tropical to Julian). +** +** . FK4 positions include the E-terms of aberration, to simplify +** the hand computation of annual aberration. FK5 positions +** assume a rigorous aberration computation based on the Earth's +** barycentric velocity. +** +** . The E-terms also affect proper motions, and in particular cause +** objects at large distances to exhibit fictitious proper +** motions. +** +** The algorithm is based on Smith et al. (1989) and Yallop et al. +** (1989), which presented a matrix method due to Standish (1982) as +** developed by Aoki et al.

Change of standard epoch from J2000.0 to B1950.0. +** +** . An intermediate transition date of 1984 January 1.0 TT. +** +** . A change of precession model. +** +** . Change of time unit for proper motion (Julian to tropical). +** +** . FK4 positions include the E-terms of aberration, to simplify +** the hand computation of annual aberration. FK5 positions +** assume a rigorous aberration computation based on the Earth's +** barycentric velocity. +** +** . The E-terms also affect proper motions, and in particular cause +** objects at large distances to exhibit fictitious proper +** motions. +** +** The algorithm is based on Smith et al. (1989) and Yallop et al. +** (1989), which presented a matrix method due to Standish (1982) as +** developed by Aoki et al. (1983), using Kinoshita's development of +** Andoyer's post-Newcomb precession. The numerical constants from +** Seidelmann (1992) are used canonically. +** +** 4) In the FK4 catalog the proper motions of stars within 10 degrees +** of the poles do not embody differential E-terms effects and +** should, strictly speaking, be handled in a different manner from +** stars outside these regions. However, given the general lack of +** homogeneity of the star data available for routine astrometry, +** the difficulties of handling positions that may have been +** determined from astrometric fields spanning the polar and non- +** polar regions, the likelihood that the differential E-terms +** effect was not taken into account when allowing for proper motion +** in past astrometry, and the undesirability of a discontinuity in +** the algorithm, the decision has been made in this SOFA algorithm +** to include the effects of differential E-terms on the proper +** motions for all stars, whether polar or not.

For example, +** JD(TT)=2450123.7 could be expressed in any of these ways, among +** others: +** +** date1 date2 +** +** 2450123.7 0.0 (JD method) +** 2451545.0 -1421.3 (J2000 method) +** 2400000.5 50123.2 (MJD method) +** 2450123.5 0.2 (date & time method) +** +** The JD method is the most natural and convenient to use in cases +** where the loss of several decimal digits of resolution is +** acceptable. The J2000 method is best matched to the way the +** argument is handled internally and will deliver the optimum +** resolution. The MJD method and the date & time methods are both +** good compromises between resolution and convenience. The limited +** accuracy of the present algorithm is such that any of the methods +** is satisfactory. +** +** 2) This function is a full implementation of the algorithm +** published by Meeus (see reference) except that the light-time +** correction to the Moon's mean longitude has been omitted. +** +** 3) Comparisons with ELP/MPP02 over the interval 1950-2100 gave RMS +** errors of 2.9 arcsec in geocentric direction, 6.1 km in position +** and 36 mm/s in velocity. The worst case errors were 18.3 arcsec +** in geocentric direction, 31.7 km in position and 172 mm/s in +** velocity. +** +** 4) The original algorithm is expressed in terms of "dynamical time", +** which can either be TDB or TT without any significant change in +** accuracy. UT cannot be used without incurring significant errors +** (30 arcsec in the present era) due to the Moon's 0.5 arcsec/sec +** movement. +** +** 5) The result is with respect to the GCRS (the same as J2000.0 mean +** equator and equinox to within 23 mas). +** +** 6) Velocity is obtained by a complete analytical differentiation +** of the Meeus model. +** +** 7) The Meeus algorithm generates position and velocity in mean +** ecliptic coordinates of date, which the present function then +** rotates into GCRS. Because the ecliptic system is precessing, +** there is a coupling between this spin (about 1.4 degrees per +** century) and the Moon position that produces a small velocity +** contribution. In the present function this effect is neglected +** as it corresponds to a maximum difference of less than 3 mm/s and +** increases the RMS error by only 0.4%. +** +** References: +** +** Meeus, J., Astronomical Algorithms, 2nd edition, Willmann-Bell, +** 1998, p337. +** +** Simon, J.L., Bretagnon, P., Chapront, J., Chapront-Touze, M., +** Francou, G. & Laskar, J., Astron.Astrophys., 1994, 282, 663 +** +** Defined in sofam.h: +** DAU astronomical unit (m) +** DJC days per Julian century +** DJ00 reference epoch (J2000.0), Julian Date +** DD2R degrees to radians +** +** Called: +** iauS2pv spherical coordinates to pv-vector +** iauPfw06 bias-precession F-W angles, IAU 2006 +** iauIr initialize r-matrix to identity +** iauRz rotate around Z-axis +** iauRx rotate around X-axis +** iauRxpv product of r-matrix and pv-vector +** +** This revision: 2023 March 20 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

The +** obliquity at J2000.0 is assumed to be the Lieske et al. (1977) +** value of 84381.448 arcsec. +** +** Both the luni-solar and planetary nutations are included. The +** latter are due to direct planetary nutations and the +** perturbations of the lunar and terrestrial orbits. +** +** 3) The function computes the MHB2000 nutation series with the +** associated corrections for planetary nutations. It is an +** implementation of the nutation part of the IAU 2000A precession- +** nutation model, formally adopted by the IAU General Assembly in +** 2000, namely MHB2000 (Mathews et al. 2002), but with the free +** core nutation (FCN - see Note 4) omitted. +** +** 4) The full MHB2000 model also contains contributions to the +** nutations in longitude and obliquity due to the free-excitation +** of the free-core-nutation during the period 1979-2000. These FCN +** terms, which are time-dependent and unpredictable, are NOT +** included in the present function and, if required, must be +** independently computed. With the FCN corrections included, the +** present function delivers a pole which is at current epochs +** accurate to a few hundred microarcseconds. The omission of FCN +** introduces further errors of about that size. +** +** 5) The present function provides classical nutation. The MHB2000 +** algorithm, from which it is adapted, deals also with (i) the +** offsets between the GCRS and mean poles and (ii) the adjustments +** in longitude and obliquity due to the changed precession rates. +** These additional functions, namely frame bias and precession +** adjustments, are supported by the SOFA functions iauBi00 and +** iauPr00. +** +** 6) The MHB2000 algorithm also provides "total" nutations, comprising +** the arithmetic sum of the frame bias, precession adjustments, +** luni-solar nutation and planetary nutation. These total +** nutations can be used in combination with an existing IAU 1976 +** precession implementation, such as iauPmat76, to deliver GCRS- +** to-true predictions of sub-mas accuracy at current dates. +** However, there are three shortcomings in the MHB2000 model that +** must be taken into account if more accurate or definitive results +** are required (see Wallace 2002): +** +** (i) The MHB2000 total nutations are simply arithmetic sums, +** yet in reality the various components are successive Euler +** rotations. This slight lack of rigor leads to cross terms +** that exceed 1 mas after a century. The rigorous procedure +** is to form the GCRS-to-true rotation matrix by applying the +** bias, precession and nutation in that order. +** +** (ii) Although the precession adjustments are stated to be with +** respect to Lieske et al. (1977), the MHB2000 model does +** not specify which set of Euler angles are to be used and +** how the adjustments are to be applied. The most literal +** and straightforward procedure is to adopt the 4-rotation +** epsilon_0, psi_A, omega_A, xi_A option, and to add DPSIPR +** to psi_A and DEPSPR to both omega_A and eps_A. +** +** (iii) The MHB2000 model predates the determination by Chapront +** et al. (2002) of a 14.6 mas displacement between the +** J2000.0 mean equinox and the origin of the ICRS frame. It +** should, however, be noted that neglecting this displacement +** when calculating star coordinates does not lead to a +** 14.6 mas change in right ascension, only a small second- +** order distortion in the pattern of the precession-nutation +** effect. +** +** For these reasons, the SOFA functions do not generate the "total +** nutations" directly, though they can of course easily be +** generated by calling iauBi00, iauPr00 and the present function +** and adding the results. +** +** 7) The MHB2000 model contains 41 instances where the same frequency +** appears multiple times, of which 38 are duplicates and three are +** triplicates. To keep the present code close to the original MHB +** algorithm, this small inefficiency has not been corrected. +** +** Called: +** iauFal03 mean anomaly of the Moon +** iauFaf03 mean argument of the latitude of the Moon +** iauFaom03 mean longitude of the Moon's ascending node +** iauFame03 mean longitude of Mercury +** iauFave03 mean longitude of Venus +** iauFae03 mean longitude of Earth +** iauFama03 mean longitude of Mars +** iauFaju03 mean longitude of Jupiter +** iauFasa03 mean longitude of Saturn +** iauFaur03 mean longitude of Uranus +** iauFapa03 general accumulated precession in longitude +** +** References: +** +** Chapront, J., Chapront-Touze, M. & Francou, G. 2002, +** Astron.Astrophys. 387, 700 +** +** Lieske, J.H., Lederle, T., Fricke, W. & Morando, B. 1977, +** Astron.Astrophys. 58, 1-16 +** +** Mathews, P.M., Herring, T.A., Buffet, B.A. 2002, J.Geophys.Res. +** 107, B4.

For example, +** JD(TT)=2450123.7 could be expressed in any of these ways, +** among others: +** +** date1 date2 +** +** 2450123.7 0.0 (JD method) +** 2451545.0 -1421.3 (J2000 method) +** 2400000.5 50123.2 (MJD method) +** 2450123.5 0.2 (date & time method) +** +** The JD method is the most natural and convenient to use in +** cases where the loss of several decimal digits of resolution +** is acceptable. The J2000 method is best matched to the way +** the argument is handled internally and will deliver the +** optimum resolution. The MJD method and the date & time methods +** are both good compromises between resolution and convenience. +** +** 2) The nutation components in longitude and obliquity are in radians +** and with respect to the equinox and ecliptic of date. The +** obliquity at J2000.0 is assumed to be the Lieske et al. (1977) +** value of 84381.448 arcsec. (The errors that result from using +** this function with the IAU 2006 value of 84381.406 arcsec can be +** neglected.) +** +** The nutation model consists only of luni-solar terms, but +** includes also a fixed offset which compensates for certain long- +** period planetary terms (Note 7). +** +** 3) This function is an implementation of the IAU 2000B abridged +** nutation model formally adopted by the IAU General Assembly in +** 2000. The function computes the MHB_2000_SHORT luni-solar +** nutation series (Luzum 2001), but without the associated +** corrections for the precession rate adjustments and the offset +** between the GCRS and J2000.0 mean poles. +** +** 4) The full IAU 2000A (MHB2000) nutation model contains nearly 1400 +** terms. The IAU 2000B model (McCarthy & Luzum 2003) contains only +** 77 terms, plus additional simplifications, yet still delivers +** results of 1 mas accuracy at present epochs. This combination of +** accuracy and size makes the IAU 2000B abridged nutation model +** suitable for most practical applications. +** +** The function delivers a pole accurate to 1 mas from 1900 to 2100 +** (usually better than 1 mas, very occasionally just outside +** 1 mas). The full IAU 2000A model, which is implemented in the +** function iauNut00a (q.v.), delivers considerably greater accuracy +** at current dates; however, to realize this improved accuracy, +** corrections for the essentially unpredictable free-core-nutation +** (FCN) must also be included. +** +** 5) The present function provides classical nutation. The +** MHB_2000_SHORT algorithm, from which it is adapted, deals also +** with (i) the offsets between the GCRS and mean poles and (ii) the +** adjustments in longitude and obliquity due to the changed +** precession rates. These additional functions, namely frame bias +** and precession adjustments, are supported by the SOFA functions +** iauBi00 and iauPr00. +** +** 6) The MHB_2000_SHORT algorithm also provides "total" nutations, +** comprising the arithmetic sum of the frame bias, precession +** adjustments, and nutation (luni-solar + planetary). These total +** nutations can be used in combination with an existing IAU 1976 +** precession implementation, such as iauPmat76, to deliver GCRS- +** to-true predictions of mas accuracy at current epochs. However, +** for symmetry with the iauNut00a function (q.v. for the reasons), +** the SOFA functions do not generate the "total nutations" +** directly. Should they be required, they could of course easily +** be generated by calling iauBi00, iauPr00 and the present function +** and adding the results. +** +** 7) The IAU 2000B model includes "planetary bias" terms that are +** fixed in size but compensate for long-period nutations. The +** amplitudes quoted in McCarthy & Luzum (2003), namely +** Dpsi = -1.5835 mas and Depsilon = +1.6339 mas, are optimized for +** the "total nutations" method described in Note 6. The Luzum +** (2001) values used in this SOFA implementation, namely -0.135 mas +** and +0.388 mas, are optimized for the "rigorous" method, where +** frame bias, precession and nutation are applied separately and in +** that order. During the interval 1995-2050, the SOFA +** implementation delivers a maximum error of 1.001 mas (not +** including FCN). +** +** References: +** +** Lieske, J.H., Lederle, T., Fricke, W., Morando, B., "Expressions +** for the precession quantities based upon the IAU /1976/ system of +** astronomical constants", Astron.Astrophys. 58, 1-2, 1-16.

The MJD method and the date & time methods are both +** good compromises between resolution and convenience. +** +** 2) In accordance with normal star-catalog conventions, the object's +** right ascension and declination are freed from the effects of +** secular aberration. The frame, which is aligned to the catalog +** equator and equinox, is Lorentzian and centered on the SSB. +** +** The proper motions are the rate of change of the right ascension +** and declination at the catalog epoch and are in radians per TDB +** Julian year. +** +** The parallax and radial velocity are in the same frame. +** +** 3) Care is needed with units. The star coordinates are in radians +** and the proper motions in radians per Julian year, but the +** parallax is in arcseconds. +** +** 4) The RA proper motion is in terms of coordinate angle, not true +** angle. If the catalog uses arcseconds for both RA and Dec proper +** motions, the RA proper motion will need to be divided by cos(Dec) +** before use. +** +** 5) Straight-line motion at constant speed, in the inertial frame, is +** assumed. +** +** 6) An extremely small (or zero or negative) parallax is overridden +** to ensure that the object is at a finite but very large distance, +** but not so large that the proper motion is equivalent to a large +** but safe speed (about 0.1c using the chosen constant). A warning +** status of 1 is added to the status if this action has been taken. +** +** 7) If the space velocity is a significant fraction of c (see the +** constant VMAX in the function iauStarpv), it is arbitrarily set +** to zero. When this action occurs, 2 is added to the status. +** +** 8) The relativistic adjustment carried out in the iauStarpv function +** involves an iterative calculation.

Proper motion +** and radial velocity are, strictly, in terms of barycentric +** coordinate time, TCB. For most practical applications, it is +** permissible to neglect the distinction between TCB and ordinary +** "proper" time on Earth (TT/TAI). The result will, as a rule, be +** limited by the intrinsic accuracy of the proper-motion and +** radial-velocity data; moreover, the supplied pv-vector is likely +** to be merely an intermediate result (for example generated by the +** function iauStarpv), so that a change of time unit will cancel +** out overall. +** +** In accordance with normal star-catalog conventions, the object's +** right ascension and declination are freed from the effects of +** secular aberration. The frame, which is aligned to the catalog +** equator and equinox, is Lorentzian and centered on the SSB. +** +** Summarizing, the specified pv-vector is for most stars almost +** identical to the result of applying the standard geometrical +** "space motion" transformation to the catalog data. The +** differences, which are the subject of the Stumpff paper cited +** below, are: +** +** (i) In stars with significant radial velocity and proper motion, +** the constantly changing light-time distorts the apparent proper +** motion. Note that this is a classical, not a relativistic, +** effect. +** +** (ii) The transformation complies with special relativity. +** +** 3) Care is needed with units. The star coordinates are in radians +** and the proper motions in radians per Julian year, but the +** parallax is in arcseconds; the radial velocity is in km/s, but +** the pv-vector result is in au and au/day. +** +** 4) The proper motions are the rate of change of the right ascension +** and declination at the catalog epoch and are in radians per Julian +** year. The RA proper motion is in terms of coordinate angle, not +** true angle, and will thus be numerically larger at high +** declinations. +** +** 5) Straight-line motion at constant speed in the inertial frame is +** assumed. If the speed is greater than or equal to the speed of +** light, the function aborts with an error status. +** +** 6) The inverse transformation is performed by the function iauStarpv. +** +** Called: +** iauPn decompose p-vector into modulus and direction +** iauPdp scalar product of two p-vectors +** iauSxp multiply p-vector by scalar +** iauPmp p-vector minus p-vector +** iauPm modulus of p-vector +** iauPpp p-vector plus p-vector +** iauPv2s pv-vector to spherical +** iauAnp normalize angle into range 0 to 2pi +** +** Reference: +** +** Stumpff, P., 1985, Astron.Astrophys. 144, 232-240. +** +** This revision: 2023 May 4 +** +** SOFA release 2023-10-11 +** +** Copyright (C) 2023 IAU SOFA Board.

The formulae for the two cases are +** developed from Hohenkerk & Sinclair (1985) and Rueger (2002). +** The IAG (1999) optical refractivity for dry air is used. +** +** d) The formula for beta, the ratio of the scale height of the +** atmosphere to the geocentric distance of the observer, is +** an adaption of Equation (9) from Stone (1996). The +** adaptations, arrived at empirically, consist of (i) a small +** adjustment to the coefficient and (ii) a humidity term for the +** radio case only. +** +** e) The formulae for the refraction constants as a function of +** n-1 and beta are from Green (1987), Equation (4.31). +** +** References: +** +** Crane, R.K., Meeks, M.L.
