Column meaning:
TIME
Prior to 1962, 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 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._(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 /r =
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. Angular units: DEGREES.
The '/r' column is a Sun-relative code, output for observing sites
with defined rotation models only.
/T indicates target trails Sun (evening sky)
/L indicates target leads Sun (morning sky)
NOTE: The S-O-T solar elongation angle is the total separation in any
direction. It does not indicate the angle of Sun leading or trailing.
S-T-O =
Sun-Target-Observer angle; target's apparent PHASE ANGLE as seen at
observer's location at print time. Units: DEGREES
