************************************************************************************************************************************************* Column meaning: TIME Prior to 1972, times are UT1. 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 TDB uniform time scale is used internally. Conversion between TDB 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._(a-apparent)__DEC. = Airless apparent right ascension and declination of the target 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) dRA*cosD d(DEC)/dt = The rate of change of target apparent RA and DEC (airless). d(RA)/dt is multiplied by the cosine of the declination. Units: ARCSECONDS PER HOUR T-mag N-mag = Comet's approximate apparent visual total magnitude ("T-mag") and nuclear magnitude ("N-mag") by following definitions: T-mag = M1 + 5*log10(delta) + k1*log10(r) N-mag = M2 + 5*log10(delta) + k2*log10(r) + phcof*beta Units: none r rdot = Target apparent heliocentric range ("r") and range-rate ("rdot") as seen by observer. Units: AU and KM/S delta deldot = Target apparent range ("delta") and range-rate ("delta-dot") relative to observer. Units: AU and KM/S S-O-T = Sun-Observer-Target angle; target's apparent solar elongation seen from observer location at print-time. If negative, the target center is behind the Sun. Units: DEGREES S-T-O = Sun-Target-Observer angle; target's apparent PHASE ANGLE as seen at observer's location at print time. Units: DEGREES Computations by ...
