finals2000A.data| Content | Quick-look weekly estimates of the EOP determined by combining the most recently available observed and modeled data (including VLBI 24-hour and intensive, GPS, and AAM). The combination process involves applying systematic corrections and slightly smoothing, in order to remove the high frequency noise. finals2000A.data contains the values from IERS Bulletin A for x/y pole, UT1-UTC, LOD, dX, dY, their errors and predictions for next 365 days for x/y pole, UT1-UTC, dX and dY as well as the values from IERS Bulletin B for x/y pole, UT1-UTC, dX, dY at daily intervals since 01. January 1992. Celestial pole offsets (dX, dY) are related to the IAU2000A precession/nutation theory. |
