      The CATALOG directory contains mission, host, instrument,       
reference, personnel, and data set PDS catalog objects for            
this archive volume.  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 a maximum of 80            
characters per line.  Each line is delimited with a carriage-         
return (ASCII 13) line-feed (ASCII 10) pair in positions 79-80.       
                                                                      
     The templates are:

     A description of the data set contained in the archival          
volumes.  The file includes information on the two primary            
data types included in the archive collection -- the ODR and          
the TDF.  Brief discussions of the quality of the data are            
included where a judgment can be made.  The data types [and           
their directory names in the archive volume] are:
