    Re: Nautical Almanac question
    From: Frank Reed CT

    Stan you asked:
    "Does anyone know how the  altitude correction tables for the moon at the
    back of the Nautical Almanac are  created.  What I am asking is how you go from
    refraction, parallax,  semi-diameter, and augmentation (?) to the Main and
    Add'l corrections shown in  the upper and lower parts of the tables."
    
    Sure. May I ask, how far have  you gotten so far? If you've already figured
    out most of it, it would be a  little easier to fill in the missing parts than
    repeat the whole thing from  scratch.
