This INDEX directory contains five files:                                     
                                                                              
  INDXINFO.TXT:         The file you are reading now                          
  INDEX.TAB:            An index file for this archive volume                 
  INDEX.LBL:            The PDS label file for INDEX.TAB                      
  CUMINDEX.TAB:         An index file, cumulative over this archive           
                        volume set                                            
  CUMINDEX.LBL:         The PDS label file for CUMINDEX.TAB                   
                                                                              
The index file INDEX.TAB contains a single record for each MCS DDR data       
product file present in this archive volume.  The index file CUMINDEX.TAB     
contains a single record for each MCS DDR data product file delivered to PDS, 
including this archive volume.  The following description applies to both     
files.                                                                        
                                                                              
The index files are formatted to facilitate easy ingest into a variety of     
database management systems.  All fields are fixed length, separated by       
commas, and all character fields are enclosed in double quotation marks (").  
Each record contains 155 bytes of ASCII character data (1 character = 1 byte).
Bytes 154 and 155 contain the ASCII carriage return and line feed characters, 
respectively.  This allows the table to be treated as a fixed length record   
file on computers that suport this file type, and to be treated as a normal   
text file on other computer systems.

size, and locations, can be found in the PDS label files INDEX.LBL and
