Content | Earth orientation parameters: x/y pole, UT1-UTC, LOD, dX, dY (smoothed values at 1-day intervals) with respect to IAU 2006/2000A precession-nutation model and consistent with ITRF2014.EOP 14 C04 is updated two times per week.Relative to 08 C04, changes in the EOP series from 2011 consist of1) A small bias in x-pole and y-pole under -50 +/- 25 microarcseconds in the sense of x or y (14 C04) - x or y (08 C04);2) Small changes in UT1-TAI that are under 5 microseconds; and3) Small changes in celestial pole offsets that are under 20 microarcseconds.The data are stored in yearly files since 1962 and in one file 1962-now. |
