Each point gives the Lunar gravity anomaly in milligals, which is the difference of the model gravity on the geoid from the gravity on a reference sphere with semi-major-axis = 1738.0 km, GM = 4902.8003055554 km**3/s**2, and zero rotation rate. The JGGRX_0660B_ANOM_320 gravity anomaly is computed from a truncated GL0660B solution (from degree 2 up to degree 320). The reference for the GL0660B gravity field is KONOPLIVETAL2013, published in the Journal of Geophysical Research with the DOI number 0.1002/jgre.20097. map_object 0 2 Last Index Fastest The Digital Map contains values of the gravity anomaly. The values can be obtained by multiplying the sample in the map by SCALING_FACTOR and then adding OFFSET. One milligal equals 0.01 mm/s/s.
