DESCRIPTION               = "This data product is a map of data counts
   for the gridded data product of the corresponding filename,
   of Mercury at a resolution of 64 pix/deg by 64 pix/deg,
   based on altimetry data acquired through the Mapping Phase
   by the MLA instrument. The gridded topographic data products
   are the source for this data set, which contains the number of
   observations per pixel that have been used to produce it.
   The map is in the form of a binary table with one row for each
   0.015625 degrees of latitude, pixel registered.  Map values
   are relative to a radius of 2439.4 km.

   This label describes three objects.  The first is a JP2 file of
   the corresponding uncompressed .IMG file. A jpeg 2000 compression is used 
   to render the image.  The second is the uncompressed IMG file.  The third
   is an auxiliary xml file that contains extensible markup language that is 
   interpreted by GDAL readers (www.gdal.org).
