DESCRIPTION               = "This data product is a shape map (radius)
   of the Moon at a resolution of 10m/pix by 10m/pix, true at the
   pole in polar stereographic (spherical) projection, based on altimetry
   data acquired by the LOLA instrument.  The LOLA Laser 1 and 2 data
   through mission phase LRO_ES_03 are the source for this gridded product.
   These data use adjusted orbits; each orbital track was geometrically
   adjusted so as to minimize the misfit to a polar map created from all
   other tracks, in an iterative fashion.  The adjustment removes residual
   artifacts resulting from dynamically-integrated orbit solutions.  Prior 
   to adjustment, the RDRs upon which these products are based are based on 
   the GRAIL 660 primary field.

   Individual points have been compared to a filtered dataset and about 
   0.004% of the data have been flagged as erroneous, improving the quality 
   over previous releases.
   
   The ground tracks are interpolated using the Generic Mapping Tools
   programs 'mapproject', 'blockmedian' and 'surface'. The map is in the
   form of a binary table.  Map values are relative to a radius of 1737.4 km.

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