These ASCII text files provide high-level information about the MSL mission, spacecraft (instrument host), instrument(s), references, and data sets in this archive. The catalog files in this directory are updated as more precise information becomes available. For the latest version of these files, please consult the Planetary Data System Data Set Catalog available on the PDS web site at: http://pds.jpl.nasa.gov/ The following files are found in this directory: File Description --------------------- ----------------------------------- CATINFO.TXT this file MARDI_EDR_IMG_DS.CAT This file contains data set objects for the MSL MARDI Image products. The EDRs are considered Level 2 or Edited Data (equivalent to NASA Level 0). EDRs are reconstructed from Level 1 or Raw Data. MARDI_EDR_VID_DS.CAT This file contains data set objects for the MSL MARDI Video products. The EDRs are considered Level 2 or Edited Data (equivalent to NASA Level 0). EDRs are reconstructed from Level 1 or Raw Data. MARDI_RDR_IMG_DS.CAT This file contains data set objects for the MSL MARDI Image products. The RDRs are considered Level 4 or Resampled. RDRs are created from EDR images and contain irreversibly transformed data due to the nature of JPEG decompression. MARDI_RDR_VID_DS.CAT This file contains data set objects for the MSL MARDI Video products. The RDRs are considered Level 4 or Resampled. RDRs are created from EDR images and contain irreversibly transformed data due to the nature of JPEG decompression. MARDI_INST.CAT This file describes the MSL MARDI instrument and its scientific objectives. MARDI_PERSON.CAT This file lists the Principal Investigator (PI) for the MARDI instrument. MARDI_REF.CAT This file lists bibliographic citations, specifically for the MARDI, for works cited in these catalog files. MSL_INSTHOST.CAT This file describes the MSL spacecraft (instrument host) that carried the instrument. MSL_MISSION.CAT This file provides a brief description of the MSL mission. It includes a chronology of events, a definition of mission phases, and the mission objectives. MSL_REF.CAT This file lists general, mission-wide, bibliographic citations for works cited in these catalog files. SOFTWARE.CAT This file describes the software, dat2img, provided to read, extract, and decompress a MMM EDR into an IMG viewable by NASAView.
