    Bill:
    
    I had a chuckle at your finding all those acronyms, but I was taught that
    nautical language had to be unambiguous, so that no command could be
    misunderstood. I think the same goes for CN.  "Height" is for height of
    eye, and not altitude."Body" refers to a celestial body, and not the body
    of the observer. Distortion of that precise language could lead to
    confusion.
