DESCRIPTION                  = "This file contains a digital,
1 X 1 degree resolution grid of the errors in the vertical gravity
accelerations of the moon.  It is a 360 x 180 grid from 89.5 to -89.5
degrees latitude, and -180.0 to 179.0 degrees longitude.  The errors were
computed by projecting the full covariance of the JGL075D gravity
solution onto the surface of the satellite.  The observation is vertical
gravity acceleration uncertainty in milligals at the surface referenced
to a sphere of 1738.0 km radius."
