BULLETIN B 212
(IAU 2000)
3 october 2005
==============================================================================
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
as long as necessary.
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.

The data of this section are smoothed, with the same characteristics as
UT1R in section 1. They are corrected for the effects of zonal tides with
periods up to 35 days. Section 2 gives the daily interpolation of D.

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.
Units : 0.001" for x,y , 0.0001s for UT1, 0.001" for dX, dY.
