SOFTWARE ON THE MGS MOLA ARCHIVE VOLUMES

The Software directory on MGS MOLA archive volumes contains two programs
for accessing data in PEDR files. They are:

   MPROF - an IDL script that generates topography profiles
   PEDR2TAB - a Fortran program that generates an ASCII table of
     PEDR data (replaces an earlier program called PDCODE)

The programs on this archive volume are the latest versions that were
available. They work with the MOLA PEDRs as described in the PEDR
Software Interface Specification version 2.7. Updates to these
programs, and possibly additional software, are posted as they become
available on the PDS Geosciences Node web site at
http://wwwpds.wustl.edu.

This software is provided for Sun/UNIX and PC/Windows platforms, and a
Macintosh version of PEDR2TAB is also provided. The MOLA Science Team
web site has the same software plus variants for other architectures;
see http://ltpwww.gsfc.nasa.gov/tharsis/software.html. Questions about
the software on this archive volume may be addressed to the PDS
Geosciences Node at geosci@wunder.wustl.edu.  For information about
additional versions of this software, or about the format of MOLA data
products, contact Gregory Neumann, MOLA Science Team, at
Gregory.Neumann@GSFC.NASA.GOV.


1. MPROF

MPROF is a script for use with the commercial image processing
software package IDL, a product of Research Systems, Inc., 2995
Wilderness Place, Boulder, Colorado 80301
(http://www.rsinc.com). MPROF can be used only on a computer that has
IDL software installed. The script generates topography profiles from
PEDR data products.  Instructions for using the script are in the file
mprfinfo.txt in the MPROF directory.

MPROF was written by C. David Brown, Dept. of Earth and Planetary 
Sciences, Washington University.


2. PEDR2TAB

PEDR2TAB is a program that reads MOLA PEDR files and produces an ASCII
table of selected fields, one line for each altimetry shot
detected. The user may choose to see all ranges, or only those that
are/are not ground hits, in a selected region. The user may output any
of eight groups of MOLA instrument values. By default, topography,
range, planetary radius, and flags are output. The program is
written in Fortran 77 with MIL-STD-1753 and other extensions.

PEDR2TAB was written by Gregory Neumann, MOLA Science Team,
NASA/Goddard Space Flight Center.
