DESCRIPTION                   = "This data product is a shape
 map of the south pole of Mars at a resolution of 512 pixels per degree,
 based on altimetry data acquired by the Mars Global Surveyor MOLA
 instrument and accumulated over the course of the primary and extended
 mission. The MOLA Precision Experiment Data Records (PEDRs) are the
 source for this data set. Map coordinates use the IAU2000 reference system.
 The binned data include all MOLA nadir observations from the Mapping Phase
 through the Primary and Extended missions, from the end of aerobraking
 in February 1999 through June 2001.  Additionally, off-nadir observations
 of the north pole are included from 87 S latitude and southward, taken
 during during Mapping from 87 S to the pole. The number of samples in each
 bin is given in the MEGC_S_512.IMG data product.
   Since the projection of radius to a polar map view is nonstandard, it
 should be pointed out that there is no flattening assumed and the MAP_SCALE
 is approximate. The pixel {x, y} coordinates are given by
 2*sin[0.5*(Pi-colatitude)]*{sin[longitude],-cos[longitude]}*MAP_RESOLUTION
 +0.5*{(LINE_SAMPLES+1),(LINES+1)}. The first pixel lies at 73.1519S, 315E."
