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

   In the SPICE system, the PC-kernels contain planetary attitude and
   body shape information. The PCK kernel includes 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. SPICELIB's PCK software
   is 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. The SPICE system toolkit for a number of computer
   platforms is located in the SOFTWARE subdirectory of the main
   directory of this CD. Refer to the PCK.REQ document provided with
   the toolkit to get more information on how to access PC-kernel
   data.


Mars Pathfinder PC-kernel contained in this dataset
===================================================

   This data set includes a single PC-Kernel file containing planetary 
   constants values used by MPF project during the mission. 


PC-kernel file naming schema
============================

   The PC-kernel file in this dataset is a SPICE text kernel format
   file, MPF_PCK.TPC, that conforms to the UNIX text end-of-line
   convention.
   
   The label for the PC-kernel file is stored separately in file named
   MPF_PCK.LBL.
