    Sorry, Bill.
    
    The inputs I use are the body (including limb in case of sun) and
    time, after previously entering the DR and date and time, etc.
    
    There would be some re-arrangement of one or more of the nav formulas
    that would give the azimuth as a result of the equivalents of the same
    data but I don't know it. Perhaps one of the more mathematically
    focused could derive it. Let us know if you find out.
