DESCRIPTION               = "This data file accompanies the topographic
   and radius maps of Mars, IEG0125T.IMG and IEG0125R.IMG, at a
   resolution of 0.25 by 0.25 degrees. It contains the number of
   observations per pixel (i.e., per bin) that have been used to produce
   the topography and radius maps. This map of 'counts' is in the form
   of a binary table with one row for each 0.25-degree latitude, from 0
   to 360 degrees East longitude and 90 to -90 degrees latitude. A total
   of approximately 333 million observations are represented.  
      Note that MOLA uses a different orbit numbering scheme from that
   used by the MGS Project. The Project reset its orbit counter to 1 at
   the beginning of the Mapping Phase. Since MOLA had already generated
   products identified by orbit number prior to the Mapping Phase, it
   was decided to use the Project orbit number plus 10000 to identify
   MOLA Mapping Phase products, thereby avoiding duplicate product IDs.
   Subtract 10000 from a MOLA mapping phase orbit number to determine
   the equivalent MGS Project orbit number. Since the MOLA topographic
   data are cumulative over the whole mission, the orbit number range
   for these products spans both the Orbit Insertion and Mapping
   Phases."
