    Moon's Augmented/Flattened SD from NA's Correction Tables
    From: David Iwancio
    Date: 2022 Apr 20, 01:36 -0700

    Writing this down here because I keep forgetting it.

    • Find the first correction for the nearest entry to the altitude of the upper limb
      • Simply being somewhere in the right column is usually good enough
    • Add 30.0'
    • Subtract the correction for an altitude 30' lower (i.e. the approximate altitude of the lower limb
    • Add the L correction
    • Subtract the U correction
    • Divide the result by 2 to get the SD
