This photo was used in Figure 2-60 of the Analysis of Apollo 8 Photography and Visual Observations (SP-201), which has the following caption:

Control point 2.

Text from Analysis of Apollo 8 Photography and Visual Observations referring to this figure is as follows:

For Apollo 8, a target for optical sightings on the lunar far side was called a control point (CP). Three control points were selected before the flight to make sightings easier. The control point identified as CP-1 was located 20° from the evening terminator and CP-2 was located 60° from the evening terminator. The control point identified as CP- 3 was located 60° from the morning terminator. The command module pilot (CMP) exercised an option of selecting sighting targets in real time and selected new targets for CP-1 and CP-2. These control points can be positively identified on Apollo 8 photography (figs. 2-59 and 2-60), and the same points were probably sighted on all three revolutions.

CP-2 was calculated at the time to be at Lat. -9.7016, Long. +163.2246, with a radius of 1738.093 km.
This photo was also used in Figure 2-71 (b) of the Analysis of Apollo 8 Photography and Visual Observations, which has the following caption:

Apollo 8 photographs used in model of convergent photography. (a) Apollo 8 frame 2703, (b) Apollo 8 frame 2704.

Text from Analysis of Apollo 8 Photography and Visual Observations referring to this figure is as follows:

Model of Convergent Photography (Magazine C)
Photographs 2703 and 2704 from magazine C, as shown in figure 2-71, were selected for the second model. This particular model was selected for evaluating the Apollo 8 convergent photography for photogrammetric processing. These are also black-and-white photographs taken with the 80-mm lens. This model covers the entire crater 302 at 11° S, 162° W. The scale of this model was also obtained from measurements made on Lunar Orbiter II medium-resolution frame 33. The Sun angles were 41° and 42°, respectively.
A contour map of this model, as shown in figure 2-72, was compiled using the same procedure for leveling as in the first model. The original map scale is 1:200,000, and the contour interval is 250 meters, larger than the first model. This may show the difference between vertical and convergent photography. The scale of the full-sized map is a 8.4480 magnification of the 1:1,689,600 model scale.
