                    INDEX Directory Contents

     The INDEX directory contains a tabular index of the data products
on this volume (INDEX.TAB), accompanied by a detached PDS label that
describes the format of the index table (INDEX.LBL). As this data set
is published on only one volume, the customary cumulative index is
omitted.



              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.
