    The original database describes this as: Description: Oblique view southeastward along the southwestern rim of the Crater Alphonsus. Smooth terrain at the right side of the frame is the eastern Sea of Clouds. Deep shadows at the top of the photograph are in the Crater Alpertragius. The dark-halo-crater area on the western floor of the Alphonsus, considered as a candidate site during the selection of landing sites for the Apollo 16 and 17 missions, is at the lower left corner of the photograph. The albedo contrast between the normal Alphonsus floor and dark-halo material is not striking at this viewing angle and low Sun elevation. The dark-halo material is approximately 100km south of the ground-track as this photograph was exposed. Note the large pockets of flat terrain similar to the Alphonsus floor that are perched at intermediate levels up the terraced western wall of Alphonsus. Image was taken during Revolution 30 of the Apollo 16 mission. Original film magazine was labeled V,filmtype was SO-368 (Color Exterior),250mm lens with a sun elevation of 8 degrees. Approximate Altitude was 111 km. Principal Point Latitude was 14.3S by Longitude 4.8W,with a camera tilt of 50 and an azimuth of 150 degrees.
