Steve L, I think there can be 2 hour angle solutions for a single azimuth. I think one h.a. will be less than 90 degrees, and the other greater than 90. See attached DeltaCad file. I wish I could comment on the derivation of your math, but I am unfamiliar with your arctan, arc cos solution for ha. I hate to say it, but this is where spherical trig will yeild the answers. Any takers?
