                    INDEX Directory Contents

     The INDEX directory contains tabular index files, accompanied by 
detached PDS labels, for the data products on this volume.
It also contains cumulative index tables for products on
this volume and on previously released MOLA archive volumes. The 
following files are found in this directory.

EGCMIDX.LBL  - PDS label for EGCMIDX.TAB.
EGCMIDX.TAB  - Cumulative index table for EGDR products on this volume
               and on previously released MOLA archive volumes.
               Note that the same EGDR product may be published on
               several successive volumes. This table contains an
               entry for each volume, even if the volumes contain
               the same EGDR product. 
EGINDEX.LBL  - PDS label for EGINDEX.TAB.
EGINDEX.TAB  - Index table for EGDR products on this volume only.
PEDCMIDX.LBL - PDS label for PEDCMIDX.TAB.

               Note that the same SHADR product may be published on
               several successive volumes. This table contains an
               entry for each volume, even if the volumes contain
               the same SHADR product.

              Notes on Using the Index Tables

     An index table contains one row (record) for each data product 
it describes. The table is formatted so that it 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 and line feed 
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 file with extension ".LBL" and the same name as an index 
table is a PDS label file that describes the content and structure of 
the fields in the index table. This description includes the name of 
each field, its format, and a brief definition.  The values for start 
byte and number of bytes listed in the label file do not include commas 
between fields or quotation marks surrounding character fields.
