                    INDEX Directory Contents

     The INDEX directory contains a tabular index file,
accompanied by a detached PDS label, for each data set on 
the MGS Science Sampler.

The following files are found in this directory.

INDXINFO.TXT - The file you are reading.

INDEX.TAB - An index table for the data products on the MGS
  Science Sampler volume.

INDEX.LBL - A PDS label describing INDEX.TAB.

              Notes on Using the Index Table

     The index table contains one row (record) for each data product 
on the volume. 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 INDEX.LBL file 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.
