| Data Set Abstract |
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. |
