DESCRIPTION                    = "This file contains a digital,
1 X 1 degree resolution map of the error in the free-air gravity
accelerations 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 ~1.7 to 21.7
milligals.  It is a 360 x 180 grid from 89.5 to -89.5 degrees
latitude, and 0.5 to 359.5 degrees longitude."
