    Jared, I wish you would give us an example. I don't understand your
    explanation. For example, it's unclear to me what you mean by
    "position". Is it the observer's position or the body's geographical
    position (the point on Earth with that body at the zenith)? That's one
    of the several things I didn't get.
    Just pretend I'm from Missouri and show me your method with a fully
    worked example.
