Selenodetic control network

Details for identifying the first 66 reference points of a selenodetic control network are presented. These reference points consist of craters having diameters larger than 8 km and which are therefore detectable on most plates used so far in lunar photogrammetric studies. The distribution of the adopted 211 reference points on Blagg-Mueller (1935) maps is given along with the Blagg-Mueller catalog number of each crater. The correspondence is indicated among the Blagg-Mueller number, the Lunar and Planetary Laboratory Catalog number, and the frame number of Lunar Orbiter IV photographs on which the craters have been studied.
