DESCRIPTION                  = "This file contains a digital,
1 X 1 degree resolution grid of free-air gravity accelerations
of Venus.  It is a 360 x 180 grid from 89.5 to -89.5 degrees
latitude, and 240 to 240 degrees longitude, increasing from west to east.  
The gravity anomalies are derived from the 120th-degree and -order 
spherical harmonic gravity model, SHG120.  The observation is free-air
gravity in milligals."
