      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 an ASCII stream file.

     The files are:

CATINFO.TXT

     A brief description of the files within the CATALOG directory
(this file).


MISSION.CAT

     A brief description of the mission.  It includes a chronology
of events, definition of mission phases, and science objectives.


INSTHOST.CAT

     A brief description of the Cassini spacecraft and the DSN components.


INST.CAT

     An overview of the spacecraft radio system used for GWE2 on Cassini,
and a summary description of the Deep Space Network instrumentation which
supports radio science experiments.


PROJREF.CAT
     A listing of references contained in the MISSION.CAT and INSTHOST.CAT
files.


REF.CAT

     A listing of references used elsewhere in the catalog files and of
references that might be generally useful in working with these data.


PERSON.CAT

     A listing of key people involved in analyzing the GWE2 radio data
and in producing the archival data set.


DATASET.CAT

     A description of the data set contained in the archival volumes.  The
