DESCRIPTION               = "This data product is a shape map (radius)
   of the Moon at a resolution of 4 pix/deg by 4 pix/deg,
   based on altimetry data acquired through mission phase LRO_NO_13
   by the LOLA instrument. The preliminary LOLA data are the source for
   this data set. The ground tracks were interpolated using the Generic
   Mapping Tools programs 'surface' and 'grdblend'.  The map is in
   the form of a binary table with one row for each
   0.25 degrees of latitude, pixel registered.  Map values
   are relative to a radius of 1737.4 km.

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