This subdirectory contains the indices for the NS CDR and DDR data 
products. The following files are contained in the index subdirectory.

INDXINFO.TXT: Identifies and describes the function of each file in the
index subdirectory. This includes a description of the structure and
contents of each index table in the subdirectory and usage notes.

CDR_INDEX.TAB: The CDR index file is organized as a table. In the table, 
there is a row for each CDR data product on the volume. The table columns 
contain parameters that describe the observation, instrument, and spacecraft 
parameters.

CDR_INDEX.LBL: Detached PDS label for CDR_INDEX.TAB. It contains the 
INDEX_TABLE object which identifies and describes the columns of the NS 
index table.

DDR_INDEX.TAB: The DDR index file is organized as a table. In the table, 
there is a row for each DDR data product on the volume. The table columns 
contain parameters that describe the observation, instrument, and spacecraft 
parameters.

DDR_INDEX.LBL: Detached PDS label for DDR_INDEX.TAB. It contains the 
INDEX_TABLE object which identifies and describes the columns of the NS 
index table.

MD5.TAB: Provides the MD5 checksum (message digest) for each file in the      
archive, with the exception of the MD5.TAB file itself.                       
                                                                              
MD5.LBL: Detached PDS label for MD5.TAB.
