                          INDEX subdirectory content

The INDEX directory contains tabular index files describing the content of 
the data volume. Each tabular index is accompanied by a detached PDS label. 
The index files present depend upon the files in the data volume.

The files included in the INDEX subdirectory are:

INDXINFO.TXT: the file you are reading.

INDEX.TAB: main INDEX table listing all label files.

INDEX.LBL: PDS Label for the main INDEX table.

N.B. The INDEX.TAB file contains columns for the RELEASE_ID and REVISION_ID. 
This is a system used by the PSA to incrementally build up a data set and to 
provide a mechanism by which files can be updated without reconstructing the 
entire data set. The system is not used by all missions. For those missions 
not using the concept, a default value of RELEASE_ID=0001 REVISION_ID=0000 
is used in the INDEX label and table.


                 Notes on Using the Index Tables
                 -------------------------------
Each 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 PDS label file for each table 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.
