DESCRIPTION                  = "
 This file contains a digital map of the Mars geoid 
derived from the spherical harmonic coefficientsof the NASA GSFC
MROMGM0032 Mars gravity field. Each point is the Mars geoid height
error in meters above a reference ellipsoid (semi-major-axis = 3396.0 km,
GM = 4.282837519531400D+13 m**3/s**2, 1/flattening = 196.877360, and 
rotation rate = 7.088218066303858E-05 rad/s).

The GGMRO_095A_GEOID_080  geoid map is computed from a truncated
MROMGM0032 model (from degree 2 up to degree 80).

 The map is produced by Frank Lemoine at GSFC for the
 MRO Gravity Science Team."
