The MGS SPICE Data Archive; Mapping Data: Cycles 4,5,6 ======================================================================== Introduction ============ This document provides an overview of this volume of the Mars Global Surveyor SPICE Data Archive, including a complete listing of the volume contents. This volume contains navigation and ancillary data in the form of SPICE System kernel files for the Mars Global Surveyor (MGS) spacecraft during the 4th, 5th and 6th 28-day cycles of the Mapping Phase of the mission. See the file MISSION.CAT in the CATALOG directory for a description of the various phases of the mission. The SPICE kernel files contain geometric and much other ancillary information needed to recover the full value of science instrument data. In particular SPICE kernels provide spacecraft and planetary ephemerides, instrument mounting alignments, spacecraft orientation, spacecraft sequences of events, data needed for certain time conversions, etc. Data in the SPICE kernel files can be accessed using the NAIF (Navigation and Ancillary Information Facility) software necessary to read these files. Volume Format ============= This volume has been formatted according to the ISO-9660 level 2 Interchange Standard. This volume does not contain any Extended Attribute Records (XAR). Thus, some VAX/VMS users may have problems accessing files on this volume. File Formats ============ All text documents and other meta information files such as descriptions, PDS object definitions and detached PDS labels are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of the record. This allows the files to be read by MS-DOS/Windows, Unix, and VMS operating systems. The data files on this version of the disk were prepared to be used under a UNIX environment. Therefore all SPICE text kernel files are UNIX text files, with a line feed character (ASCII 10) at the end of the line, and all SPICE binary kernels files are UNIX binary files in which bit pattern structures for double precision and integer numbers follow IEEE standard. Volume Contents =============== Files on this volume are organized into a set of subdirectories below the top-level directory. The following table shows the structure and content of these directories. In the table, directory names are enclosed in square brackets ([]). See the *INFO.TXT files in each directory for specific information on the files in the directory.
