    Re: H.O 211 math error
    From: Joe Shields
    Date: 1999 Feb 26, 10:44 PM

    Many thanks for your responses.  Kind of scarry that I could make such
    an easy math error.  I'm usually so concerned with possible errors in
    the As and Bs looked up in H.O 211 that I guess I just kept
    overlooking the error in LHA.  I have H.O. 249, but am on a kick right
    now to see how accurate I can get using the approx. Sun decl./Eq. of
    Time table that came with my Mark 3 Davis sextant, the condensed
    Ageton table (Bayless), and the altitude correction page and the time
    to arc conversion page (both from the Nautical almanac).  The whole
    thing takes up 4 double-sided 8 1/2 * 11 sheets of paper.  Re-doing
    some sights using this bare-bones kit has opened my eyes as to how
    accurate you can get with so little to carry around.  That is, if one
    can subtract correctly. Thanks again.   -- Joe
