    D correction
    From: Richard Bash

    Hello. I am living in Hot Springs, Arkansas, and am studying
    celestial on my own. Have several books, including Bowditch.
    I am unclear about the so-called "d correction." It seems the d
    number in the dailt pages of the Nautical Almanac should really
    be called a "d factor" or something similar. Mary Blewitt's
    book says to use this d factor to get into Table 5 of H.O. 249.
    My confusion stems from no one else mentioning Table 5 (except
    H.O. 249 itself).
    Can/would someone explain to me, at the 8th grade level, about
    the d factor for sun, moon and planet shots.
    Thanks in advance. E-mail is fine (dickbash[at]bashlaw.com). You
    have a fine resource here. Hope I am accepted as a list member.
