Table 2 RMS of orbit differences between predictions and reconstruction in total position and along the line-of-sight between Grasse and LRO. Orbit predictions and time periods are the same as in Fig. 6

From: First two-way laser ranging to a lunar orbiter: infrared observations from the Grasse station to LRO’s retro-reflector array
