*********************************************************************************************************************************************
Column meaning:
TIME
Times PRIOR to 1962 are UT1, a mean-solar time closely related to the
prior but now-deprecated GMT. Times AFTER 1962 are in UTC, the current
civil or "wall-clock" time-scale. UTC is kept within 0.9 seconds of UT1
using integer leap-seconds for 1972 and later years.
Conversion from the internal Barycentric Dynamical Time (TDB) of solar
system dynamics to the non-uniform civil UT time-scale requested for output
has not been determined for UTC times after the next July or January 1st.
Therefore, the last known leap-second is used as a constant over future
intervals.
Time tags refer to the UT time-scale conversion from TDB on Earth
regardless of observer location within the solar system, although clock
rates may differ due to the local gravity field and no analog to "UT"
may be defined for that location.
Any 'b' symbol in the 1st-column denotes a B.C. date. First-column blank
(" ") denotes an A.D. date.
CALENDAR SYSTEM
Mixed calendar mode was active such that calendar dates after AD 1582-Oct-15
(if any) are in the modern Gregorian system. Dates prior to 1582-Oct-5 (if any)
are in the Julian calendar system, which is automatically extended for dates
prior to its adoption on 45-Jan-1 BC. The Julian calendar is useful for
matching historical dates. The Gregorian calendar more accurately corresponds
to the Earth's orbital motion and seasons. A "Gregorian-only" calendar mode is
available if such physical events are the primary interest.
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 center
with respect to an instantaneous reference frame defined by the Earth equator
of-date (z-axis) and meridian containing the Earth equinox of-date (x-axis,
EOP-corrected IAU76/80). Compensated for down-leg light-time delay,
gravitational deflection of light, stellar aberration, precession & nutation.
Note: equinox (RA origin) is offset -53 mas from the of-date frame defined
by the IAU06/00a P & N system.
Units: RA in hours-minutes-seconds of time, HH MM SS.ff{ffff}
DEC in degrees-minutes-seconds of arc, sDD MN SC.f{ffff}
'APmag S-brt' =
The asteroids' approximate apparent airless visual magnitude and surface
brightness using the standard IAU H-G system magnitude model:
APmag = H + 5*log10(delta) + 5*log10(r) - 2.5*log10((1-G)*phi_1 + G*phi_2)
For solar phase angles >90 deg, the error could exceed 1 magnitude. For
phase angles >120 degrees, output values are rounded to the nearest integer to
indicate error could be large and unknown. For Earth-based observers, the
estimated dimming due to atmospheric absorption (extinction) is available as
a separate, requestable quantity.
Surface brightness is the average airless visual magnitude of a
square-arcsecond of the illuminated portion of the apparent disk. It is
computed only if the target radius is known.
Units: MAGNITUDES & MAGNITUDES PER SQUARE ARCSECOND
'r rdot' =
The Sun's apparent range ("r", light-time aberrated) and range-rate ("rdot")
relative to the target center, as seen by the observer. A positive "rdot" means
the target center was moving away from the Sun, negative means moving toward
the Sun. Units: AU and KM/S
'delta deldot' =
Apparent range ("delta", light-time aberrated) and range-rate ("delta-dot")
of the target center relative to the observer. A positive "deldot" means the
target center is moving away from the observer, negative indicates movement
toward the observer. Units: AU and KM/S
'S-O-T /r' =
Sun-Observer-Target apparent SOLAR ELONGATION ANGLE seen from the observers'
location at print-time.
The '/r' column provides a code indicating the targets' apparent position
relative to the Sun in the observers' sky, as described below:
Case A: For an observing location on the surface of a rotating body, that
body rotational sense is considered:
/T indicates target TRAILS Sun (evening sky: rises and sets AFTER Sun)
/L indicates target LEADS Sun (morning sky: rises and sets BEFORE Sun)
Case B: For an observing point that does not have a rotational model (such
as a spacecraft), the "leading" and "trailing" condition is defined by the
observers' heliocentric ORBITAL motion:
* If continuing in the observers' current direction of heliocentric
motion would encounter the targets' apparent longitude first, followed
by the Sun's, the target LEADS the Sun as seen by the observer.
* If the Sun's apparent longitude would be encountered first, followed
by the targets', the target TRAILS the Sun.
Two other codes can be output:
/* indicates observer is Sun-centered (undefined)
/? Target is aligned with Sun center (no lead or trail)
The S-O-T solar elongation angle is numerically the minimum separation
angle of the Sun and target in the sky in any direction. It does NOT indicate
the amount of separation in the leading or trailing directions, which would
be defined along the equator of a spherical coordinate system.
Units: DEGREES
'Cnst' =
Constellation ID; the 3-letter abbreviation for the name of the
constellation containing the target centers' astrometric position,
as defined by IAU (1930) boundary delineation. See documentation
for list of abbreviations.
