The index directory on this volume contains information about the             
data products stored on the CD.  It contains both the required PDS            
data product index and an index of all observations and events                
listed in those product files.  The index files are designed for              
easy ingestion into most data base management systems.  Fields are            
separated by comma delimiters and non-numeric fields are enclosed             
in double quote characters (").                                               
                                                                              
INDEX.TAB    - This is the required PDS data product index.  It               
               lists each data product file with basic physical               
               parameters and time coverage.                                  
                                                                              
INDEX.LBL    - The PDS label for the INDEX.TAB file                           
                                                                              
OBSINDEX.TAB - This index into the data files lists each individual           
               observation or event recorded, along with several              
               observational parameters.

The following files were added in Summer 2011 for use in long-term            
maintenance:
