1 X 1 degree resolution map of the error in the Geoid of
Venus.  This error map was computed by projecting the full
covariance of the SHG120 gravity solution onto the surface of the
planet. The errors range from ~0.1 to 2.3 meters.  It is a 360 x 180
grid from 89.5 to -89.5 degrees latitude, and 0.5 to 359.5
degrees longitude."
