Gravity map of <a href="https://en.wikipedia.org/wiki/Mare_Fecunditatis" class="extiw" title="en:Mare Fecunditatis">Mare Fecunditatis</a> (red=high, blue=low). From description in JMARS: "<i>digital map of the gravity anomaly derived from the JPL GL0660B model of the Moon's gravity field.  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</i>".
