 IAK Overview
---------------------------------------------------------------------------

  This kernel contains constants and parameters used in Integrated
  Software for Imagers and Spectrometers (ISIS), created and managed by the 
  USGS Astrogeology Research Program in Flagstaff, AZ. For more information 
  about the constants derived here, please see:

      of the Lunar Reconnaissance Orbiter Camera

      Corrections in ISIS Using Lunar Reconnaissance Orbiter Narrow Angle

 LROC CK Definitions:
---------------------------------------------------------------------------

  These are the parameters required for writing c-kernels.  Isis will
  create a ck with the same frame endpoints as the mission ck.  For
  the LRO spacecraft the ck frame is LRO_SC_BUS (-85000), and the
  ck reference frame is J2000 (1).

 LROC OBSERVER/TARGET SWAPPING, STELLAR ABERRATION & LIGHT TIME CORRECTION:
---------------------------------------------------------------------------

  A future release of ISIS will support accurate light time measurements to
  the surface.  The constants below define the proper settings to use when 
  working with LROC NAC and WAC images at this time (20 November 2012).
  
  For now, the light time correction is disabled.  Turning it on with the 
  current software will cause sizable (>100 m) offsets when map projecting
  an image. Please see [2] for more information regarding these settings.
