     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).

     The files are:

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

INSTHOST.CAT
     A description of the Clementine spacecraft and a very brief
overview of the NASA Deep Space Network.

INST.CAT
     An overview of the laser ranging instrument (LIDAR) used for
obtaining topographic data.

DATASET.CAT
     A description of the LIDAR data set, parameters,
processing, data coverage/quality.

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

PERSON.CAT
     A listing of key people involved in generating and
processing the archival data set.
