I have horizontal coordinates calculated, but they might be wrong (both in how I call NOVAS functions and the JS code itself) because I think I'm mixing up equinox of date coordinates with J2000 coordinates for (RA,DEC). Fixed bug that caused excessive estimate of angular error: right ascension and azimuth are like longitudes -- they matter less as an object approaches the poles. Scale such longitudinal errors by the cosine of the latitudinal counterpart.
