The Moon is the hardest body to reduce, because it is so close. Its parallax (the difference between its direction from you and from the Earth's center) is up to a degree, and changes with its distance, which the almanac gives as HP (horizontal parallax) every hour.

GHA: hour + increment from the Moon column (the Moon moves only about 14°19′ an hour) + v correction. v is large and given for every hour.
Dec: hour + d correction; d is given for every hour too, and can be over 15′.
Altitude: the two-part Moon table. The first correction by Ha; the second from the same column by HP, with the L figure for the lower limb or U for the upper. Add both; for the upper limb subtract 30′.

Ha 33°27′, HP 58.4′, lower limb: first correction 57.3′, second 5.9′; total +63.2′.

Upper limb, same sight: 57.3′ + 4.0′ − 30′ = +31.3′.

Moon: altitude correction

Ha column

First correction by Ha, then the second from the same column by HP, L or U. Add both; subtract 30′ for the upper limb.

The app's Moon table is built the way the Nautical Almanac's is, and matches every entry of the 2024 almanac from 5° up within 0.1′.
