Abstract

The Apollo whole-disk lunar photographs, with spacecraft lunar nadirs about 70?? from the center of mean face, have considerable selenodetic potential provided that the requirements of resolution and precision can be met. Uncertainties in the internal camera geometry degrade the precision and make selenodetic applications doubtful, but selenographic work based on the assumption of a rigorously spherical moon makes lesser demands on the data and is still possible with useful accuracy. The selenographic method is fully developed here and applied to photographs 2505 and 2506 of Apollo 8 to produce a catalog of 635 positions. Of these 206 are farside and extend to 130?? East Longitude. A new type of 5-character position word, appropriate for the entire lunar sphere, is used to define sequence in the catalog. ?? 1971.
