          COMMENTS ON LUNAR PROSPECTOR LEVEL 0 CD-ROMS

     This document contains a cumulative set of comments and errors
concerning the Lunar Prospector Level 0 data archive published on
CD-ROMs.

1.  Comment on merged telemetry files

     In most cases, the first record of a merged telemetry file is the
same as the last record of the previous file.  There are, however,
cases where there are time gaps between two merged telemetry files
and, thus, no overlapping records.  There are also a few cases where
two files do not have overlapping records.


2.  ATTITUDE.TAB file on volume LP_0001

     Attitude determinations from 1/7/98 through 1/15/98 are based on
sun sensor data only.  Determinations starting on 1/16/98 are based on
a combination of sun sensor data, Earth-Moon limb sensor data, and the
definitive ephemeris.


3.  PDS catalog objects on volume LP_0001.

     The catalog objects on this volume for the five science
instruments are somewhat brief.  This is because at the time that the
volume was released, published papers about the instruments were not
available.  When instrument papers are published by the Lunar
Prospector Science Teams, the catalog objects will be revised and
expanded.  The revised catalog objects will be included on later
volumes.
