    N.A. Altitude Correction Table
    From: Herbert Prinz
    Date: 2001 Apr 27, 10:41 AM

    Dear All,
    
    I just realize that I don't understand the Altitude Correction Table 10�
    to 90� for the Sun on page A2 in the Nautical Almanac.
    
    Does anybody know whether the exact formula (algorithm) that generates
    this table has been published? I can't seem to reproduce it with the
    calculator formulas given in the Almanac itself. Nor is it consistent
    with the results I get when I correct the sun observation for refraction
    by means of the star table and then apply horizontal parallax and
    average SD according to season... What am I missing?
    
    Best regards

    P.S.
    
    Speaking of the sun: Has anybody on the list observed it in the last few
    days? Quite remarkable.
