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 Calendar dates are given in the modern Gregorian system, extended prior to its 1582-Oct-15 adoption. The Gregorian calendar more closely corresponds to physical Earth seasons and orbital motion, but can differ by up to 10 days with historical records made under the prior Julian calendar, more if the Julian calendar was extended prior to its 45-Jan-1 BC adoption to label the historical event. Select "mixed" calendar mode if correlation with historical dates prior to A.D. 1582 is important. NOTE: "n.a." in output means quantity "not available" at the print-time. 'TDB-UT,' = Difference between the uniform Barycentric Dynamical time-scale and the Earth-rotation dependent Universal Time. Prior to 1962, the difference is with respect to UT1 (TDB-UT1) and the 0.002 second maximum amplitude distinction between TT and TDB is not maintained. For 1962 and later, the difference is with respect to UTC (TDB-UTC) and periodic terms less than 1.e-6 second are ignored. Values beyond the next July or January 1st may change if a leap-second is later required by the IERS. Values from the present date forward through the next ~78 days are predictions. Beyond that prediction interval, the last prediction is taken as a constant for all future dates. Units: SECONDS 'ObsEcLon, ObsEcLat,' = Observer-centered IAU76/80 ecliptic-of-date longitude and latitude of the target centers' apparent position, with light-time, gravitational deflection of light, and stellar aberrations.
