Standard Rapid EOP Data since 02. January 1973 (IAU2000)

finals2000A.all| 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.all 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 02. January 1973.Celestial pole offsets (dX, dY) are related to the IAU2000A precession/nutation theory. |
