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.___(J2000.0)___DEC. = J2000.0 astrometric right ascension and declination of target. Corrected for light-time. Units: DEGREES delta deldot = Target apparent range ("delta") and range-rate ("delta-dot") relative to observer at print-time. "deldot" is a projection along the line-of-sight from the coordinate center and indicates direction of motion. A positive deldot means the target is moving away from the observer/coordinate-center. A negative deldot means the target is moving towards the observer. Units: AU and KM/S Computations by ...
