      The DOCUMENT directory holds files which document the Venus Range-Fix   
data set.  Documents in the directory are of two types.                       
                                                                              
      Simple documents containing only ASCII text are defined as PDS TEXT     
objects.  These are files with 80 characters per line, the last two           
characters being the ASCII carriage-return line-feed pair.  These PDS TEXT    
objects have a simple PDS label prepended to the file; file names end with    
the *.TXT extension.  DOCINFO.TXT (this file) is one such file.  Other files  
include:                                                                      
                                                                              
  DESCRIPT.TXT   A brief description of the Venus Range-Fix measurements      
                 and their scientific context.

      Complex documents include both ASCII text and figures.  The Radio       
Science Handbook, Volume 4, is such a document.  It is defined by a detached  
label (HANDBK4.LBL) which describes both its ASCII component (HANDBK4.ASC)    
and the set of figures (59 files with the suffix *.TIF).  Although this       
volume of the Radio Science Handbook was written several years after the      
Venus Range Fix observations, much of the equipment and many of the           
procedures were the same.  The document(s) describing the Venus Range Fix     
data acquisition were not in electronic form when this data set was           
archived.
