                       INDEX Directory Contents

The INDEX directory contains tabular index files, accompanied by
detached PDS labels, intended for database use.  The following files
are found in this directory:

INDXINFO.TXT - The file you are now reading.

INDEX.LBL    - Detached PDS label for INDEX.TAB.
INDEX.TAB    - Abbreviated index table for the current Mars Exploration
               Rover 2 EDR archive volume.  Contains image location
               information and primary search criteria.

                   Notes on Using the Index Tables

The index table in this directory, INDEX.TAB, contains one row (or
record) for each data file in the archive.  If the archive is stored
on more than one CD-ROM or DVD-ROM, then INDEX.TAB lists data files on
this volume and the optional cumulative index table, CUMINDEX.TAB,
lists data files on all the volumes.

Index tables are formatted so that they can be read directly into
many data management systems.  All fields are separated by commas, and
character fields are enclosed in double quotation marks (").
Character fields are left justified, and numeric fields are right
justified.  Each record ends with ASCII carriage return <CR> and line
feed <LF> characters.  This allows the table to be treated as a fixed
length record file on computers that support this file type and as a
normal text file on other computers.

The ".LBL" files are PDS label files that describe the content and
structure of the fields in the tables, including field name,
format, and description.
