    Sorry, somehow the attachment didn't get attached.  Hope it is now.
    
    The red curve is from a vessel sailing north at 10 knts.  The red stars show 
    data from the moving vessel corrected to what would be observed from a 
    stationary vessel (the black line).   The excellent agreement with the exact 
    black H-curve is quite impressive.
