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.
 
SOLAR PRESENCE
  Time tag is followed by a blank, then a solar-presence symbol:

        '*'  Daylight (refracted solar upper-limb on or above apparent horizon)
        'C'  Civil twilight/dawn
        'N'  Nautical twilight/dawn
        'A'  Astronomical twilight/dawn
        ' '  Night OR geocentric ephemeris

LUNAR PRESENCE
  The solar-presence symbol is immediately followed by a lunar-presence symbol:

        'm'  Refracted upper-limb of Moon on or above apparent horizon
        ' '  Refracted upper-limb of Moon below apparent horizon OR geocentric
             ephemeris
 
 R.A._(ICRF/J2000.0)_DEC =
   J2000.0 astrometric right ascension and declination of target. 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 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
 
 Azi_(a-appr)_Elev =
   Airless apparent azimuth and elevation of target. Corrected for light-time,
the gravitational deflection of light, stellar aberration, precession and
nutation. Azimuth measured North(0) -> East(90) -> South(180) -> West(270),
elevation with respect to plane perpendicular to local zenith direction.
TOPOCENTRIC ONLY. Units: DEGREES
 
 a-mass =
   Relative optical airmass. Topocentric EARTH sites, ABOVE HORIZON ONLY.
Unitless.
 
 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
 
 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 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
 
 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
 
 PsAng PsAMV =
   The position angles of the extended Sun->target radius vector ("PsAng")
and the negative of the target's heliocentric velocity vector ("PsAMV"),
as seen in the observer's plane-of-sky, measured CCW (east) from reference
frame North Celestial Pole. Small-bodies only. Units: DEGREES.
 
 Cnst =
   Constellation ID; the 3-letter abbreviation for the constellation name of
target's astrometric position, as defined by IAU (1930) boundary delineation.
See documentation for list of abbreviations.
 
 GlxLat =
   Observer-centered Galactic System II (post WW II) latitude of the target's
apparent position. Corrected for light-time, the gravitational deflection of
light and stellar aberration. Units: DEGREES
