Nautical Almanac question

    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.

    Thanks in advance.

    Stan
