    You should be puzzled.  I hosed up. Mistyped it once, copied and pasted 3
    times, changed it for each case (and did than incorrectly in the last case)
    and viola, off in deep space.
    
    The initial Z should read "LHA"
    
    Zn is determined as per 229 usual rules:
    
    N. Lat
    L.H.A. greater than 180.....Zn = Z
    L.H.A. less than 180....... Zn = 360-Z
    
    A. Lat
    L.H.A. greater 180..........Zn = 180-Z
    L.H.A. less than 180........Zn = 180+Z
    
    Apologies to all,
    
    Bill
