    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."
