    Re: Hughes Tables.
    From: Dave Walden
    Date: 2009 Jul 15, 18:41 -0700

    Near 40 deg N, 77 deg W, on 13 July 2009 at 9:00:00 UT.  Formalhaut corrected, 20 deg 24.3'.
    
    Using HO 208 (Dreisonstok), Hughes Tables (Comrie), and Line of Position Book 
    (Weems) all with interpolation "by eye".  Same method, same numbers, same 
    answers (luckily!), different layouts.
    
    Also show Aerial and Marine Navigation Tables (Gengrich).
