General information about SPICE FRAMES kernels
==============================================

   In the SPICE system, FRAMES kernel contains a set of information
   required to define various frames used in a particular mission,
   sources of orientation and origin location information for these
   frames and inter-connections between these frames and other frames
   supported within the SPICE system.

   The frame definitions information contained in the file can be
   utilized by a collection of FORTRAN 77 subroutines that are part of
   the SPICELIB library or C functions that are part of the CSPICE
   library to provide correct interpretation for the SPICE data from
   SP- and C-kernels. The SPICE system toolkit for a number of computer
   platforms or information regarding how it can be obtained is located
   in the "/software" subdirectory of the main directory of this data set.
   
   Refer to the "frames.req" document provided with the toolkit or
   available from the NAIF Node of PDS if SPICE toolkit is not included
   with this data set to get more information about definition and
   usage of the frames within SPICE system.


MGS FRAMES Kernels contained on this volume
===========================================

   The following Frames Kernel file is included on this volume (only name 
   portion of the file name is shown on the right; the extension of all 
   file names is ".tf"):

           mgs_vVV        main MGS Frames kernels providing the
                          complete set of frame definitions for the
                          Mars Global Surveyor (MGS) spacecraft, its
                          structures, and science instruments.
   
           mgs_hga_vVV    MGS High Gain Antenna Frames kernel files 
                          containing definitions for HGA dish and
                          structure frames and for all (transmit and
                          receive) Low Gain Antenna (LGA) frames;

   The main MGS frame kernels supersede the MGS HGA frames kernels; if
   multiple FK files pf the same kinds are present, the one with the
   latest version (VV) supersedes all previous versions.


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

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