INTRODUCTION                                                                  
====================================================================          
                                                                              
     This volume contains archival data produced during the Satellite         
Field and Mass Determination Experiment carried out using the Galileo         
spacecraft (in cruise to Jupiter) and Earth-based receiving stations          
of the NASA Deep Space Network (DSN).                                         
                                                                              
     The volume contains data from a limited of Satellite Field and Mass      
Determination Experiments. Volume identifiers and the range of dates          
covered by a data file are

These data were originally contained on five separate volumes                 
(GORS_0501 - GORW_0505).

VOLUME SET INFORMATION                                                        
====================================================================          
                                                                              
     This volume contains Satellite Field and Mass Determination Experiment   
from Ganymede, Callisto, and Europa raw data. The volume structure is         
illustrated in the diagram below.  In cases where the directory would         
contain no files, the directory itself will be omitted from the volume.       
                                                                              
     Data are arranged chronologically.  Data files not repeated within the   
volume, although two files may overlap in time during a period in which two   
DSN stations are tracking the  spacecraft simultaneously.

     A cumulative list of errors and changes is maintained in the             
file ERRATA.TXT at the root level of the volume.

VOLUME FORMAT                                                                 
====================================================================          
                                                                              
     The volume is organized according to the PDS standard for "one           
data set, one volume."  This file (AAREADME.TXT), a PDS volume                
object definition (VOLDESC.CAT), and the listing of errors and                
changes (ERRATA.TXT) are included at the root level.  The following           
directories of descriptive material are also at the root level:               
                                                                              
          CALIB     contains tables of low-gain antenna pattern               
                    measurements.                                             
                                                                              
          CATALOG   contains descriptive files for cataloging each            
                    of the data types included in this disc.                  
                                                                              
          DOCUMENT  contains a plain text Software Interface                  
                    Specification (SIS) for each data type, if                
                    available, plus other documentation.                      
                                                                              
          GEOMETRY  contains NAIF SPK, CK, and SCLK files giving              
                    spacecraft and planetary ephemerides during the           
                    observation period and attitude information for           
                    reconstructing the spacecraft antenna pointing.           
                                                                              
          INDEX     contains index information on each of the data            
                    files included in this disc; it also includes a           
                    cumulative index to all files in this volume              
                    set.                                                      
                                                                              
The remaining directories at the root level contain data files and            
detached PDS labels.                                                          
                                                                              
                                                                              
====================================================================          
FILE FORMAT                                                                   
====================================================================          
                                                                              
     All data files on the disc are accompanied by detached                   
PDS labels, which describe their contents.  PDS TEXT objects                  
include attached labels.                                                      
                                                                              
     Minimal labels were used to facilitate transfer of the data to           
an archive; construction of full labels with object definitions               
would have added significantly to the development time, possibly              
putting the total effort in jeopardy.                                         
                                                                              
     Detached labels were chosen over attached labels for simplicity          
of implementation.                                                            
                                                                              
     Labels have the same file name as the primary data file except           
for the suffix ".LBL".                                                        
                                                                              
     Detailed documentation on file structure is available                    
in Software Interface Specifications in the DOCUMENT directory.               
                                                                              
     Text files, including data files of ASCII text and all labels            
(*.LBL files) and tables (*.TAB files), are delimited by carriage-            
return (ASCII 13) line-feed (ASCII 10) pairs at the end of each               
line.
