Sorry, my fault, I "redefined" azimuth. As I found on <http://aa.usno.navy.mil/data/docs/AltAz.html#Notes> "_Azimuth_ is the angle along the horizon, with zero degrees corresponding to North, and increasing in a clockwise fashion". I posted the angle between the two lines from both points to the center of the earth. Rainer Gruber DrBob wrote: > I think azimuth is far more complicated than rainer indicated.
