SDDPT Mariner 9 UV Spectrometer Reduced Data on CD-WO

NSSDCA ID: PSPA-00204

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Description

This data set contains Mariner 9 Ultraviolet Spectrometer Reduced Data copied from magnetic tapes onto a single CD-WO volume for preservation purposes. These tapes represent the complete set of UVS EDR and SEDR final data which have been processed through UVS SAP - a program which would coorelate UVS spectra and SEDR data, interpolating if necessary and output spectra and SEDR data to these tapes (also known as MRG tapes).

Each CD-ROM disc has been formatted so that a variety of computer systems (e.g. IBM PC, Macintosh, Sun, VAX) may access the data. Specifically, the discs are formatted according to the ISO 9660 level 1 Interchange Standard, and file attributes are specified by Extended Attribute Records (XARs). The 7-track data in this dataset was padded. The 6 bit characters were padded to 8 bits by placing zeroes into the 2 high order bits. The 7-track tape data was originally written in "SNAKED" format with attached EBCDIC VICAR labels in front of the data. The file MRG_INFO.TXT located on each CD, coorelates the tape ID with the corresponding CD volume and descriptions of the tapes' contents. The tape descriptions were obtained from the exterior tape labels and available information contained in the MIPS On-line tape database.

This data set was created at JPL as part of its Science Digital Data Preservation Task (SDDPT), and a copy was provided to NSSDC for safekeeping. Numerous SDDPT data sets are not readily usable, as they represent bit copies of old data tapes and do not contain user documentation. Persons interested in ordering these data should contact the NSSDC person listed for this data set.

This SDDPT data set code 71_051A-0069, volume ID M71_6201.
