TIME

Barycentric Dynamical Time ("TDB" or T_eph) output was requested. This
continuous relativistic coordinate time is equivalent to the relativistic
proper time of a clock at rest in a reference frame comoving with the
solar system barycenter but outside the system's gravity well. It is the
independent variable in the solar system relativistic equations of motion.

TDB runs at a uniform rate of one SI second per second and is independent
of irregularities in Earth's rotation.

Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.

REFERENCE FRAME AND COORDINATES

Ecliptic at the standard reference epoch

Reference epoch: J2000.0
X-Y plane: adopted Earth orbital plane at the reference epoch
Note: IAU76 obliquity of 84381.448 arcseconds wrt ICRF X-Y plane
X-axis : ICRF
Z-axis : perpendicular to the X-Y plane in the directional (+ or -) sense
of Earth's north pole at the reference epoch.

Symbol meaning [1 au= 149597870.700 km, 1 day= 86400.0 s]:

JDTDB Julian Day Number, Barycentric Dynamical Time
EC Eccentricity, e
QR Periapsis distance, q (au)
IN Inclination w.r.t X-Y plane, i (degrees)
OM Longitude of Ascending Node, OMEGA, (degrees)
W Argument of Perifocus, w (degrees)
Tp Time of periapsis (Julian Day Number)
N Mean motion, n (degrees/day)
MA Mean anomaly, M (degrees)
TA True anomaly, nu (degrees)
A Semi-major axis, a (au)
AD Apoapsis distance (au)
PR Sidereal orbit period (day)

ABERRATIONS AND CORRECTIONS

Geometric osculating elements have NO corrections or aberrations applied.

O.K.
"Немного было во все века столь ироничных и здравомыслящих людей, как римский император Веспасиан, заявивший в 79 году по поводу очередной кометы: «Эта волосатая звезда не предвещает мне никаких бед. Скорее, она угрожает парфянскому царю. Ибо он волосат, а я лыс». "
