As I understand the matter:
Both bodies on the same vertical:
?A-factor? (cosine Moon-corner):
ZMS = 180 deg.
?B-factor? (cosine Sun-corner):
Sun above Moon:
ZSM = 180 deg.
Sun below Moon:
ZSM = 000 deg

"If the Moon is directly above the Sun (its altitude would then be 75 degrees), the angle ZMS is zero and its cosine is +1. If the Moon is directly below the Sun (necessarily at an altitude of 15 degrees), the angle ZMS is 180 degrees and its cosine is -1."Isn't it the other way around?
