    One-body fix, clarification
    From: Peter Hakel

    I should have added in my previous post that "my" LHA also differs in sign from the conventional LHA.  Mine is the angle from the local meridian to the GP meridian measured eastward as positive.  It occurs to me now that I perhaps should have called it the meridian angle t; does this conform with the standard definition?  If so, then the hour angle HA = GHA + t, and Longitude = -HA (for HA < 180), Longitude = 360 - HA (for HA > 180).

    If Ho < 0, then replace t from the inverse sine with SIGN(t)*180 - t, otherwise keep t unchanged.
