    Re: HO 211 Umland version
    From: Chuck Griffiths

    From Paul Hirose:
    
    I finally took a good look at the version of the HO 211 sight
    reduction table that Chuck Griffiths pointed out for us. Its creator,
    Henning Umland, has made the table available for download on the Web.
    
    http://home.t-online.de/home/h.umland/index.htm
    
    Some of his table's features are arguable. In my opinion there are an
    excessive number of significant digits. For example, in the A column,
    from zero to 50 degrees, there's at least one more significant digit
    than needed for interpolation to .1 minute...
    
    
    Well, I'm glad someone else found it worth looking at. I was interested to hear
    that Mr. Umland wasn't the first to attempt this approach.
    
    Chuck Griffiths
