BULLETIN B 202
(IAU 2000)
3 december 2004
==============================================================================
Following IAU Conventions 2000, IERS provides new products dX, dY, celestial
pole offsets with respect to the new IAU2000A Precession-Nutation theory.
The present Bulletin B version includes the celestial pole offsets dX, dY:
dX = X_obs - X_IAU2000A and dY = Y_obs - Y_IAU2000A
where
X_obs, Y_obs are the observed coordinates of the Celestial Intermediate
Pole (CIP) in the Geocentric Celestial Reference System, and
X_IAU2000A, Y_IAU2000A are the celestial pole coordinates provided by using
the IAU2000A Precession-Nutation theory.
The current Bulletin B including (dpsi,deps)_1980 will be maintained until
December 2004.
For more details refer to IERS Messages 38, on IAU 2000 Resolution Compliancy
Information.

Note. In UT1R, the effects of zonal tides with periods shorter than 35 days
are removed ; UT1-UT1R (smaller than 0.0025s in absolute value) should be
added after quadratic interpolation of UT1R. Section 2 of this Bulletin gives
the daily interpolation of x, y, UT1, duration of day, dX, and dY.

6 - SUMMARY OF CONTRIBUTED EARTH ORIENTATION PARAMETERS SERIES
This section gives the average precision of the individual series contri-
buting to the combination and their average agreement with it. The periods
covered start at the beginning of the first month in Section 1 and end with
the last available value in the individual series considered.
