    Re: Classification of the methods for clearing the Lunar Distances
    From: George Huxtable
    Date: 2003 Apr 7, 23:13 +0100

    Thanks to Jan Kalivoda for a masterly summary of the various lunar-distance
    correction methods, which I will print off and slip into my copy of Cotter.
    He must have a superb library available in Prague, or else has done much
    travelling to collect his information.
    
    He ends by saying-
    
    >Thank you for your corrections and supplements.
    
    There's only one comes to my mind. Under "Short", or "approximate" methods,
    he describes the lunar-distance triangle, and says-
    
    > ....But the sections mM and sS are very short (half degree at most, but
    >mostly shorter), which is essential for further procedures.
    
    As I see it, the arc mM represents the (parallax - refraction) correction
    for the Moon's altitude, and will normally be around one degree at low Moon
    altitudes, not "half degree at most".
