I think the term is “angular diameter.” (I had to look it up, as my space-word skills are rusty).

Try this, if it helps.

Apparent size works too. Angular diameter or angular distance is what we would use to measure the apparent size. Of course if you have photos taken with unknown cameras with unknown lenses and unknown zoom settings from unknown locations at unknown times when the earth and moon are in unknown positions in their orbits, it is going to be impossible six ways from Sunday to determine the actual angular distances.

I’m sure we could do research and figure out some of those variables but I doubt we could get all that information, and we certainly can’t make any useful judgements without even trying to obtain that information.

Thanks looks interesting.
