finals.daily| Content | Quick-look daily 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.daily contains for the last 90 days the values from IERS Bulletin A for x/y pole, UT1-UTC, LOD, dPsi, dEps, their errors and predictions for next 90 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. Celestial pole offsets (dPsi, dEps) are related to the IAU1980 nutation theory. |
