Magellan Spherical Harmonics, Topography, and Gravity Data

December 17, 2008. The binary spherical harmonics coefficients file SHGJ120U.B01 from Alex Konopliv, JPL, has been added to the Gravity directory of this archive.

This archive contains Magellan spherical harmonic models of Venus' gravity and topography field, and digital maps of the Bouguer anomalies, free-air gravity accelerations and errors, geoid anomalies and errors, and topography. It also contains documentation describing the products.
