Dates thereafter are UTC. Any 'b' symbol in the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D. date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system. Later calendar dates are in the Gregorian system. The uniform Coordinate Time scale is used internally. Conversion between CT and the selected non-uniform UT output scale has not been determined for UTC times after the next July or January 1st. The last known leap-second is used over any future interval. NOTE: "n.a." in output means quantity "not available" at the print-time. R.A._(ICRF/J2000.0)_DEC = J2000.0 astrometric right ascension and declination of target center. Corrected for light-time. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f) R.A._(a-apparent)__DEC. = Airless apparent right ascension and declination of the target center with respect to the Earth true-equator and the meridian containing the Earth true equinox of date. Corrected for light-time, gravitational deflection of light, stellar aberration, precession & nutation. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f) Ang-diam = The equatorial angular width of the target body full disk, if it were fully visible to the observer. Units: ARCSECONDS Computations by ...
