Line of sight (LOS) gravity data were obtained as part of the Radio Science Experiment by tracking 79 orbits of the Viking Orbiter 2. The data set consists of a table with the following columns: spacecraft latitude, longitude (degrees), accelerations, and altitude (km). The acceleration data were determined from differentiation of raw Doppler residuals and are expressed as units of mm/s**2. To obtain LOS gravity in milligals, accelerations need to be multiplied by 100. An acceleration of 1.20 mm/s**2, therefore, corresponds to 120 mgal, a large gravity anomaly.
