  Data Set Overview
  =================

  The Mars Global Surveyor spacecraft included a laser altimeter
  instrument. The primary objective of the Mars Orbiter Laser
  Altimeter (MOLA) is to determine globally the topography of Mars at
  a level suitable for addressing problems in geology and geophysics.

  The primary MOLA standard data product is the Precision Experiment
  Data Record (PEDR). (See the description for the PEDR data set, data
  set ID MGS-M-MOLA-3-PEDR-L1A-V1.0.) PEDRs are stored in binary files
  that may be accessed only by using customized software. This PEDR
  ASCII table data set was created to provide access to the PEDR data
  without the need for special software.

  Data
  ====

  One PEDR ASCII (i.e. plain text) table exists for each PEDR product.
  The ASCII table has the same name as the PEDR from which it was 
  derived, with the extension 'TAB'. Each ASCII table is described
  by a detached PDS label.

  The ASCII tables contain those data fields from the PEDRs that are
  most likely to be of interest; some of the engineering data fields
  have been omitted from the ASCII tables.  

  Processing
  ==========

  The PEDR ASCII tables were generated using the Fortran program
  PEDR2TAB developed by MOLA Science Team member Gregory Neumann.
  This software is distributed on the MOLA PEDR archive volumes 
  and is available from the PDS Geosciences Node web site
  (http://wwwpds.wustl.edu) and the MOLA Team web site 
  (http://ltpwww.gsfc.nasa.gov/tharsis/mola.html).

  The ASCII tables were generated at the Geophysics Subnode of the
  PDS Geosciences Node, Washington University, St. Louis, Missouri,
  by Jim Alexopoulos under the direction of Roger Phillips, MOLA
  Science Team member.

  Coordinate System
  =================

  See the coordinate system discussion in the description of the PEDR
  data set.

  Software
  =======

  See the Processing section above.

  Media/Format
  ============

  The PEDR ASCII tables are distributed on the CD-ROM archive volume
  with the standard product PEDRs from which they are derived. They
  may also be available electronically via the PDS Geosciences Node
  web site at http://wwwpds.wustl.edu and the MOLA Science Team web
  site at http://ltpwww.gsfc.nasa.gov/tharsis/mola.html. The format of
  the ASCII tables is compatible with PDS standards for tabular data."
