    Of course if using D=height over Earth's surface
    the result is valid only for culmination in zenith.
    Use range instead of height.
    Or make an approximate adjustment by multiplying
    Aš with sin(elevation) and cos(ang.sep.from culm.)
    (Also it works just as well if both S and D are in km, or feet...)
    ----- Original Message -----
    Aš =angular separation (degrees) = 57.3  S/D
    Where S = the separation distance in statute miles between the Shuttle  & 
    D = the distance of the two vehicles in statute miles above the Earth's
