Lee Laboratory for Atmospheric and Space Physics University of Colorado ================================================================= INTRODUCTION ================================================================= This compact disc contains archival data produced from the Viking Lander missions to Mars. The data sets were produced from the Footpad Temperature Sensor (FTS) on each Lander. Both point-by-point (VL_FTPD) and sol average (VL_AVET) versions of the data are included. ================================================================= VOLUME INFORMATION ================================================================= This disc contains two data sets as described below. Each data set is contained in one file, internally ordered by spacecraft and time. The data sets are: (1) VL_FTPD - This data set contains point-by-point temperature data from the Viking Lander 1 and 2 thermocouple footpad temperature sensors. (2) VL_AVET - This data set contains summary temperature data from the Viking Lander 1 and 2 thermocouple footpad temperature sensors. This volume follows the structure outlined below: root | |- AAREADME.TXT The file you are reading. | |- ERRATA.TXT Description of known anomalies and | errors present on this volume. | |- VOLDESC.CAT A description of the contents of this | CD_ROM volume in a format readable by | both humans and computers. | |- [CATALOG] A directory containing information | | about the Lander data sets | | | |- CATINFO.TXT Description of files in this directory. | | | |- MISSION.CAT Description of the Viking Lander | | missions. | | | |- VL1HOST.CAT Description of the Viking Lander 1 | |- VL2HOST.CAT and 2 spacecraft. | | | |- FTS_INST.CAT Description of the Lander | | Footpad Temperature Sensors. | | | |- VL_FTPD.CAT Descriptions of the data sets. | |- VL_AVET.CAT | | | |- PERS.CAT A listing of the people involved in the | | production of these data sets and | | this CD-ROM. | | | |- REFS.CAT A list of pertinent references. | |- [DATA] A directory containing the data files | and PDS labels describing the contents | of those files. | |- VL_FTPD.DAT The VL_FTPD data file. | |- VL_FTPD.LBL The PDS label describing VL_FTPD.DAT. | |- VL_AVET.DAT The VL_AVET data file. | |- VL_AVET.LBL The PDS label describing VL_AVET.DAT. ================================================================= DISC FORMAT ================================================================= This disk has been formatted so that a variety of computer systems (e.g. IBM PC, Macintosh, Sun, VAX) may access the data. Specifically, the disk is formatted according to the ISO 9660 level 1 Interchange Standard. For further information, refer to the ISO 9660 Standard Document: RF# ISO 9660-1988, 15 April 1988. ================================================================= FILE FORMAT ================================================================= All data files on this disc are accompanied by detached PDS labels, which describe their contents. PDS TEXT objects include attached labels. All PDS labels include an SFDU label in the first record. Labels have the same file name as the primary data file but have a suffix ".LBL" appended. The data files were extracted from the Planetary Atmospheres Node Data Analysis System (PANDA) at the University of Colorado. Each file is ASCII, with the number of records and record structure documented in the associated PDS labels. ================================================================= ACKNOWLEDGMENTS ================================================================= This archiving project was initiated by Steve Lee of the Planetary Data System (PDS) Atmospheres (ATM) Discipline Node (DN) at the University of Colorado. The data were provided by Jim Tillman of the University of Washington. The archival products which result from this activity will be delivered to the PDS ATM DN. Assistance in developing the structure of this volume and format of the catalog files was provided principally by Ron Joyner of PDS at JPL. ================================================================= DISCLAIMER ================================================================= Although considerable care has gone into making this volume set, errors are both possible and likely. Users of the data are advised to exercise the same caution as they would when dealing with any other unknown data set. Reports of errors or difficulties would be appreciated. Please contact one of the persons listed below. ================================================================= WHOM TO CONTACT FOR INFORMATION ================================================================= For questions concerning this volume or the data sets and documentation contained herein, contact: Steven W.
