      The CATALOG directory contains mission, host, instrument, reference,    
personnel, and data set PDS catalog objects for this archive volume.  It      
also contains a data set map projection definition.  The files follow the     
streamlined format adopted by the Planetary Data System (PDS) in late         
1993 and documented in the Planetary Data System Standards Reference          
(Version 3.1, 3 August 1994; JPL D-7669, Part 2).                             
                                                                              
     Each catalog object is in ASCII, with 72 characters per line.  Each      
line is delimited with a carriage-return (ASCII 13) line-feed (ASCII 10)      
pair in positions 71-72.                                                      
                                                                              
     Also included in the CATALOG directory is the file CATINFO.TXT (this     
file) which gives a brief description of the contents of the CATALOG          
directory.  CATINFO.TXT is the only file in the directory with 80 character   
records.  Each record is delimited with a carriage-return (ASCII 13)          
ine-feed (ASCII 10) pair in positions 79-80.
