finals.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.finals.data contains the values from IERS Bulletin A for x/y pole, UT1-UTC, LOD, dPsi, dEps, their errors and predictions for next 365 days for x/y pole, UT1-UTC, dPsi and dEps as well as the values from IERS Bulletin B for x/y pole, UT1-UTC, dPsi, dEps at daily intervals since 01. January 1992.Celestial pole offsets (dPsi, dEps) are related to the IAU1980 nutation theory. |
