    Compared to the table in Bowditch, this agrees within 0.2'. I am now
    happy. Distance to the horizon, geographic range, dip, and dip short
    all stem from one equation.

    There are few things so satisfying as when you can get several different
    useful formulas from one basic principle or equation.  Good work!
