DESCRIPTION                  = "
 This file contains a digital map of the Mars geoid heights derived from
 spherical harmonic coefficients of the NASA GMM-3 gravity field. Each
 point gives the Mars geoid height in m, which is computed with respect to
 the reference ellipsoid with semi-major-axis = 3396.0 km, 
 GM = 0.4282837285418775E+05 km**3/s**2, 1/flattening = 196.877360, and
 rotation rate = 7.088218066303858D-05 rad/s.  The GMM3_120_GEOID_90
 gravity anomaly map is computed from a truncated GMM-3 solution (from
 degree 3 up to degree 90).

 The map is produced by Antonio Genova as a postdoctoral scientist at NASA
 GSFC under the auspices of the MRO Gravity Science Team, and under the
 direction of M.T. Zuber and F.G. Lemoine.
 
 The reference for the GMM-3 gravity field is GENOVAETAL2016."
