Implementation Notes
------------------------------------------------------------------------------

   Applications that need SPICE I-kernel data must ``load'' the I-kernel file,
   normally during program initialization.

   Loading the kernel using the SPICELIB routine FURNSH causes the data items 
   and their associated values present in the kernel to become associated with
   a data structure called the ``kernel pool''. The application program may 
   then obtain the value(s) for any IK data item using the SPICELIB routines 
   GDPOOL, GIPOOL, GCPOOL. Routine GETFOV may be used if the file contains 
   instrument field-of-view (FOV) specification. See [1] for details.

   This file was created with, and can be updated with a text editor or word 
   processor.


Conventions for Specifying Data
------------------------------------------------------------------------------

   Data items are specified using ``keyword=value'' assignments [1]. All 
   keywords referencing values in this I-kernel start with the characters 
   `INS' followed by the NAIF Dawn instrument ID code, constructed using the 
   spacecraft ID number (-203) followed by the NAIF three digit ID number. 
   This number identifies the generic FC1 or FC2, one of the filters, or the 
   radiator. Generic entries for FC1 of FC2 are identical to those of filter 1
   for this is the filter most often used. The ID numbers are defined in [4]
   as follows:

               Instrument name          ID
               --------------------   -------
               DAWN_FC1               -203110
               DAWN_FC1_FILTER_1      -203111
               DAWN_FC1_FILTER_2      -203112
               DAWN_FC1_FILTER_3      -203113
               DAWN_FC1_FILTER_4      -203114
               DAWN_FC1_FILTER_5      -203115
               DAWN_FC1_FILTER_6      -203116
               DAWN_FC1_FILTER_7      -203117
               DAWN_FC1_FILTER_8      -203118
               DAWN_FC1_RAD           -203119

               DAWN_FC2               -203120
               DAWN_FC2_FILTER_1      -203121
               DAWN_FC2_FILTER_2      -203122
               DAWN_FC2_FILTER_3      -203123
               DAWN_FC2_FILTER_4      -203124
               DAWN_FC2_FILTER_5      -203125

               DAWN_FC2_FILTER_8      -203128
               DAWN_FC2_RAD           -203129

   The remainder of the keyword is an underscore character followed by the 
   unique name of the data item. For example, the f/ratio of the FC1 is
   specified by

               INS-203110_F/RATIO

   The upper bound on the length of all keywords is 32 characters.

   If a keyword is included in more than one file, or if the same keyword 
   appears more than once within a single file, the last assignment supersedes
   any earlier assignments.


Overview
------------------------------------------------------------------------------

   From [5] and [6]:

   The Dawn Framing Camera comprises a refractive lens system, a set of 7 
   band-pass filters and a clear filter with wheel mechanism, a baffle with a 
   door in front of the optics tube, a CCD at the focal plane, a thermal 
   stabilization system, and supporting electronics. The active area of the 
   Atmel/Thomson TH7888A CCD is sized 1024 x 1024 pixels or 14.34 x 14.34 mm 
   (14.00 x 14.00 micron per pixel).


Mounting Alignment
------------------------------------------------------------------------------

   Refer to the latest version of the Dawn Frames Definition Kernel (FK) [4]
   for the FC reference frame definitions and mounting alignment information.


Apparent FOV Layout
------------------------------------------------------------------------------

   This section provides a diagram illustrating the FC1 and FC2 apparent FOV
   layout in the corresponding reference frames. Pixel (0,0) is in the lower
   left corner of the image, and pixel (1023,1023) is in the top right corner.
   +X, +Y, +Z axes are defined in the Dawn Frames Definition Kernel (FK) [4].

Optical Parameters
------------------------------------------------------------------------------

   The following FC1 and FC2 nominal first order optical parameters are, 
   from [5]:

      ------------------------------------------------------------------
             parameter                    FC1                 FC2
      ------------------------------------------------------------------
      Focal Length, mm                    150.0               150.0
      f/ratio                             f/7.5               f/7.5
      IFOV, rad/pixel                     0.0000932           0.0000932
      Field of view, deg                  5.47                5.47
      ------------------------------------------------------------------

   In reality, the pixels are not square, being slightly larger in the X 
   direction than the Y direction. Focal lengths are also different for each 
   filter.
   
   The keywords below provide the optical parameters for each filter of both 
   cameras. Angular size values are given in radians. Focal length is given in
   mm, and its uncertainty is 0.01 mm. The FOV is calculated from the focal 
   length given here and the pixel dimensions specified in the ``CCD 
   Parameters'' section; it does not include the radial distortion described 
   in the ``Optical Distortion'' section. The first vector element of the IFOV
   and FOV angular size keywords refers to the X direction, the second to the 
   Y direction.

Filter Parameters
------------------------------------------------------------------------------

   This section contains FC1 and FC2 filter parameters. The FC has a single 
   broad band filter (F1) and 7 narrow band (color) filters (F2-F8).

   The following filter band center, band width, and effective wavelength (all
   in nm) data are taken from [5]. FWHM is the Full Width at Half Maximum. The
   effective wavelength is defined as the integral over the product of the 
   wavelength and the solar spectrum, divided by the integral over the solar 
   spectrum.

FOV Definitions
------------------------------------------------------------------------------

   This section contains definitions for the FC1 and FC2 FOVs. These 
   definitions are provided in a format required by the SPICE (CSPICE) 
   function GETFOV (getfov_c).
   
   The set of assignments in the data section below defines the FC1 and FC2
   FOVs with respect to the corresponding frames to be a rectangle with the
   corners defined by the first and last pixels of the first and last lines of
   the CCD and the boresight along the +Z axis. This FOV definition uses the
   FOV_ANGULAR_SIZE values from the ``Optical Parameters'' section above
   converted to degrees.

Optical Distortion
------------------------------------------------------------------------------

   This section provides optical distortion and geometric calibration data for
   FC1 and FC2, taken from [5].

   A 3d vector (P) in the camera frame is mapped into sample and line (S,L)
   coordinates in pixels through these equations:

          ( X )    FL    ( P(1) )
          (   ) = ------ (      )
          ( Y )   P(3)   ( P(2) )

   where X and Y are the horizontal and vertical distance in millimeters from 
   the center of the CCD. The X and Y directions are defined in the ``Apparent
   FOV Layout'' section. FL is the focal length in millimeters.
  
            R*R = X*X + Y*Y
          
          ( dX )      ( X*R*R )
          (    ) = E1 (       ) 
          ( dY )      ( Y*R*R )

          ( S )   ( Kx  0  ) ( X + dX )   ( S0 )
          (   ) = (        ) (        ) + (    )
          ( L )   ( 0   Ky ) ( Y + dY )   ( L0 )

   S0 and L0 refer to the position of the optical axis on the CCD in pixels, 
   and are equal to the elements of the CCD_CENTER keyword defined in the 
   ``CCD Parameters'' section. The constants Kx and Ky map millimeters to 
   pixels in the focal plane X and Y directions. They are identical to the 
   inverse of the pixel size in millimeters in the X and Y directions. The 
   pixel size in microns is defined by the PIXEL_SIZE keyword in the ``CCD 
   Parameters'' section. E1 is the first radial distortion coefficient. It is 
   a function of wavelength, and as such different for each filter. It has 
   units of 1/(mm*mm). The generic value below is that for filter 1.
