This directory contains 20 Mars Global Surveyor Orbiter Camera (MOC)
images in Planetary Data System (PDS) compressed image (IMQ) format.
To create PDS uncompressed image (IMG) format, use the program
'readmoc' which is provided on the PDS archive CD-ROMs in the software
directory.  That directory includes both a SunOS (and Solaris) and
Windows98 (DOS) version of the decompression program.  This directory
also includes a text file, 'ancillary.tab' that provides ancillary
image information in PDS format, and a JPEG version of the maps
provided by T. Parker showing the landing ellipses presently being
targeted, with the approximate locations of the 11 NA and 11 WA
context images included in this release marked in red and blue,
respectively.

NOTE_JULY_2002: Following the guidelines given me after the 3rd
Landing Site Workshop and by M. Gollombek regarding low wind sites in
Elysium and by John Grant regarding the removal of Athabasca from
further consideration, the remaining sites are Hematite, Isidis,
Gusev, and two Elysium locations.  Owing to uncertain surface albedo
conditions at the start-up of imaging of the two new Elysium sites,
this month's images contain data that are saturated by over-exposure.
Now that the albedo has been determined, future data are less likely
to be saturated.

NOTE: These data have not been validated for delivery to the PDS.
They are made available to the Mars Geoscience community and the Mars
Exploration Program to support landing site selection and validation
for the Mars Exploration Rover (MER) 2003 and later landing missions.

Please direct all inquires regarding these ellipses, and the images
provided in this directory, to the Mars Operations Office or the Mars
Exploration Office at the Jet Propulsion Laboratory:
