                    MER OPERATIONS DATA ARCHIVES

Introduction
------------

This archive volume is one of a set of volumes containing raw and
derived data from the Mars Exploration Rover mission. This volume
contains "operations" data products, which were generated by the 
Multi-Mission Image Processing Facility (MIPL) at JPL for using 
during mission operations and archived, as distinguished from 
"science" data products, which were generated by the instrument team.
For more information about science vs. operations products, see the 
text file SCI_VS_OPS.TXT in the DOCUMENT directory.


Volume Contents
---------------

MER archive volumes includes the following files and directories.

Root directory
  AAREADME.TXT - the file you are reading
  ERRATA.TXT   - notes and errata, if any
  VOLDESC.CAT  - volume description for the PDS catalog

BROWSE directory
  JPG "browse" files are grouped into sol (Mars day) number in 
  subdirectories, and then further broken down by EDR and RDR,
  e.g. BROWSE/SOL001/EDR.

CALIB directory
  CALINFO.TXT  - description of contents of this directory
  *.PDF        - instrument calibration report
  *.HTM, *.TXT - text or HTML version of the calibration report
  *.LBL        - PDS label(s) for files in this directory

CATALOG directory
  CATINFO.TXT  - description of contents of this directory
  *.CAT        - descriptions of dataset, instrument, spacecraft,
                 mission, and personnel for the PDS catalog

DOCUMENT directory

  *.HTM, *.TXT - text or HTML versions of the documentation
  SCI_VS_OPS.TXT - explanation of difference between science
                 and operational data products
  *.LBL        - PDS label(s) for files in this directory

EXTRAS directory
  "catalog" and "thumbnail" files are grouped into sol (Mars day) 
  number in subdirectories, and then further broken down by EDR 
  and RDR, e.g. EXTRAS/CATALOG/SOL001/EDR.

INDEX directory
  INDXINFO.TXT - description of contents of this directory
  INDEX.TAB    - index of all products on this volume
  INDEX.LBL    - PDS label that describes INDEX.TAB
