      The GEOMETRY directory contains ephemerides and files describing        
the pointing of the Voyager 1 High-Gain Antenna (HGA) during the radio        
occultations at Titan.                                                        
                                                                              
     Each file is accompanied by a detached PDS label.  Each label is an      
ASCII file with 80 character records.  Records are delimited by the ASCII     
carriage-return (ASCII 13) line-feed (ASCII 10) pair at the end of each       
line (positions 79 and 80).                                                   
                                                                              
     The files are:

     An ASCII file containing four PDS TABLE objects.  Three tables contain   
header information; the fourth is a set of state vectors for Voyager 1 and    
relevant solar system bodies (Sun, Earth, Saturn, Titan) during the           
Voyager 1 encounter with Titan.  This file has been converted from the        
Univac binary original, distributed on tape by the Voyager Project under the  
name CRS009.  The accompanying PDS label (file CRS009AA.LBL) describes the    
detailed format and contents of the file.

     An ASCII file containing the current SPK file (ephemerides) in NAIF      
transfer format for the Voyager 1 encounter with Saturn.  Individual lines    
in the file are delimited by ASCII carriage-return line feed pairs, which     
may need to be converted to the local default line delimiter before the       
file can be used.  The file is accompanied by a PDS minimal label; the        
label points to TK_FTP.TXT in the DOCUMENT directory for more information     
on format, content, and reader software.

     A binary file describing pointing of the Voyager 1 High-Gain Antenna     
(HGA) during the Titan encounter.  The file is accompanied by a minimal       
PDS label (filename VH009.LBL) which briefly describes its contents.  See     
VH009T.TAB for an ASCII version of the same file.

     An ASCII file containing HGA pointing information for the Voyager 1      
spacecraft during the Titan encounter.  The file is a conversion of the       
binary data contained in VH009.DAT.  PDS label VH009T.LBL describes both      
the format and content of the ASCII file.
