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 170.344 km/pix by 170.344 km/pix.
   It is based on altimetry data acquired through the Mercury Orbit 
   Year 5 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 the data
   products. The map is in the form of a binary table with one row 
   for each 0.25 degrees of latitude, pixel registered.

   This label describes an IMG file in the form of a binary resampling with
   pixel registration.  "
