Hello Folks,
I have two points on Earth at each end of a great circle path, for which I know the length in km and direction in degrees True. Also I have the RA and DEC of an object in space as seen from one of the previous points. The RA and DEC come from the setting circles of a telescope having the object centered in its view. The three points, two on Earth and one in space, determine a plane triangle. I would like to determine the angles of that triangle in the plane, in degrees. Can you help?
Thanks, Tom
