Times are UTC. Sydney is UTC + 11 hours.
So, for example, 2013-Feb-15 12:00 UTC corresponds to 2013-Feb-15 23:00 AEDT,
that is 11pm in Sydney on the night of the 15th of Feb.

R.A._(ICRF/J2000.0)_DEC =
J2000.0 astrometric right ascension and declination of target center.

Azi_(a-appr)_Elev =
Airless apparent azimuth and elevation of target center. Corrected for
light-time, the gravitational deflection of light, stellar aberration,
precession and nutation. Azimuth measured North(0) -> East(90) -> South(180) ->
West(270) -> North (360). Elevation is with respect to plane perpendicular
to local zenith direction. TOPOCENTRIC ONLY. Units: DEGREES

APmag =
Asteroid's approximate apparent visual magnitude by following definition:
APmag = H + 5*log10(delta) + 5*log10(r) - 2.5*log10((1-G)*phi1 + G*phi2).
In principle, accurate to ~ +/- 0.1 magnitude. For solar phase angles > 90 deg,
the error could exceed 1 magnitude. No values are output for phase angles
greater than 120 degrees, since the extrapolation error could be large and
unknown. Units: NONE

Illu% =
Fraction of target circular disk illuminated by Sun (phase), as seen by
observer. Units: PERCENT

Cnst =
Constellation ID; the 3-letter abbreviation for the name of the
constellation containing the target center's astrometric position,
as defined by IAU (1930) boundary delineation.
