We all have seen the nice moon HP tables provided by NAUTICAL ALMANAC website, but I wonder if you know that there are two versions... the second of which I can't make heads or tails.
The copy of the Almanac moon HP table - the one with separate lists for upper and lower limbs - makes good sense once you get used to it. However, there is another version tacked on the end of the Sun/Star/planet increment download that boggles the mind. Not only are the numbers incomparable with the Almanac HP table, but there are no upper and lower HP divisions - only a single number. That single number does not compare to UL or LL corrections noted in the Almanac version.
On the same page with the errant HP table is a Refraction table that I like to use with Gunter shots, and the DIP table seems sound, but that HP table gives me the willies... Until someone can tell me how to use it so the numbers match the Almanac version Im not going near it.
