Information

This CD-ROM contains Magellan Cycle 4 line-of-sight acceleration profile data record (LOSAPDR) products. There are 866 LOSAPDRs on this volume. The Magellan LOSAPDR files contain results from processing of radio tracking data. The Doppler shift of radio transmissions along the line-of-sight from the spacecraft to the receiver on Earth is measured, and splines are fitted to the Doppler residual values resulting from spacecraft orbit solutions. Analytical differentiation of spline results is then interpreted as local accelerations, from which the size and location of mass anomalies can be inferred.

Additional information about the Magellan gravity experiment, including the acquisition, processing, and quality of the LOSAPDR data, can be found in JPL documents that are available from the PDS Geosciences Node, Washington University, St. Louis, MO.
