Joe,

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.
