     The DOCUMENT directory contains material that would be useful for        
better understanding the observations and data products in this               
archival volume.  Because of its volume, the full DOCUMENT directory          
is included only on the final volume of the data set; an abbbreviated         
DOCUMENT directory, providing information on binary formats of certain        
data files, is included on this and other volumes.                            
                                                                              
     Also of potential interest are files in the CATALOG directory,           
intended for use in the Planetary Data System central catalog.  These         
files include descriptions of the Voyager mission, the spacecraft and         
Deep Space Network, the radio science 'instrument', and the data set.         
                                                                              
     Each file in the DOCUMENT directory is an ASCII file.  The files are:
