    Re: Interpolation to latitude

    I have been, quietly, following this discussion for a while.  
    As far as I can tell, the only reason for the interpolation of the LAT
    CORRN is to get the correction factors for the local sunrise/sunset
    times as well as the nautical and civil twilight times.  This is because
    the farther north/south of the equator you are, the more that the actual
    N/C twilight and sunrise/set times are delayed/advanced from the zone
    time meridian.
    I believe that you want to know this so that you will know when to do a
    sun rise/set sight.
    I am probably wrong, and am constantly learning more.  So when Inuik
    answers, I will learn some more.
    Thanks for the clarification!

    Hi George,
    Sorry about the delay - was busy with the American Veteran's Day
    holiday.  I'm going to answer in a 'round-a-bout way; the intent is to
    not confuse Inuik.  This is his series of postings.
