General information about SPICE PC-kernels
==========================================

   In the SPICE system, the PCK kernel provides orientation and shape
   information pertaining to extended solar system bodies such as the
   Sun, the planets, the natural satellites of the planets, comets, and
   asteroids. The most recent PC kernel file can always be obtained
   from NAIF/JPL.
   
   The purpose of the PCK kernels and associated software is to provide
   SPICE users with a convenient mechanism for supplying planetary
   physical constants to application programs. SPICE PCK routines are
   able to read files conforming to the PCK format and return to a
   calling application program both the data contained in such files
   and a small number of commonly used numeric quantities derived from
   the kernel data. Information regarding how the SPICE Toolkit can be
   obtained is located in the SOFTWARE subdirectory of the main
   directory of this dataset.
   
   Refer to the PCK.REQ document provided with the Toolkit to get more
   information on how to access PC-kernel data.

======================================

   This following PC-Kernel files are provided on this volume
   
           mars_iau2000_v0.tpc   PCK file containing only Mars and Martian 
                                 satellite constants from 2000 IAU report.

           pck00009.tpc          Generic SPICE PCK file containing 
                                 constants from the IAU 2006 report.
                                 This PCK file contains the same constants 
                                 for Mars and Martian satellites as the PCK 
                                 file mars_iau2000_v0.tpc.


Kernel File Details
===================

   The most detailed description of the data in a text PCK file is 
   provided in metadata included inside the description area of 
   the file. This information can be viewed using any text editor
   program.
