NSSDCA ID: PSPG-00181
Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)
This data set contains the Viking 1 Orbiter Master Data Records (MDR) copied from magnetic tapes to CD-WO as part of the Science Digital Data Preservation Task. Each volume in the set includes ancillary information in addition to instrument data. These MDRs were the input to the Infrared Science and Engineering Experiment Data Records. The Science Data Evaluation Board has recommended that the MDRs should be archived on higher density media because they contain the low-level data used to fill in the gaps. The data was copied from magnetic tapes that, in most cases, were at least 15-20 years old.
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 Atttribute Records (XARs). A text file correlating the tape ID, a description of the tape's contents, and the archive CD-ROM volume is included on the last disc of the series.
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 is SDDPT data set code 75_075A_0006, volume IDs VO1_4001 to V01_4023.
