This data set has been superceded by data set 96-062A-02B (PSPG-00729), see:

This data set consists of an archive of data collected by the Mars Global Surveyor (MGS) Thermal Emission Spectrometer (TES). Specifically, the set contains time sequential data records (TSDR) of the raw and calibrated thermal IR radiance spectra, the visual and thermal bolometric radiance measurements, and several atmospheric and surface properties derived from this data. Also included are the parameters that describe each observation, some downlinked diagnostic information, and the pointing and positional information derived from the project's SPICE kernels. The data products on this volume may be reprocessed at the end of the Mapping Phase of the mission.
The TES data is divided into 10 tables (OBS, RAD, BOL, GEO, POS, TLM, IFG, CMP, SRF, LMB). Each table is stored in a separate file as a PDS TABLE structure, using fixed-length binary records, with extensions to handle the variable length spectra. PDS labels are embedded at the beginning of the data files, consisting of an ASCII header that describes the contents and format of the table, and a pointer that indicates where the binary table data starts. Every record is stored with the spacecraft time, and related records can be retrieved from each table using time as a common key.
Software is included on this volume that will read the binary data and output columns of ASCII values. The software can also select records from the data that match the user's criteria. The software is provided in versions for several UNIX and PC platforms. The volume has been formatted according to the ISO-9660 level 1 Interchange Standard.
