    Re: dip, dip short, distance off with buildings, etc.

    Using a value for lift due to refraction between Franks 0.15' per nautical
    mile, and lift in feet = distance in nautical miles squared * .287, I solved
    for new values for the Bowditch Table 15 formula.
    
    Try replacing .0002419 with .0002001, and .7349 with .6079.
    
    I have done three trial runs with the new values, and they seem to approach
    reality with the average of mean refraction values derived from the two
    methods above, a least when height of eye is 0.
    
    I would be very interested in feedback.
    
    Thanks
    
    Bill
