Have you considered this? > My program takes a different approach. It does not transform a geocentric position into a topocentric one by adding this or that "correction". Rather, it computes a barycentric position of the body and of the observer and transforms both into whatever coordinate system is desired. It's all vector geometry in 3 dimensional euclidean space. So the correct answer probably is: "Yes, I have implicitly considered parallax in azimuth, but I am not aware of it." Herbert
