Information regarding these procedures is available in Chapter 5 of the IERS Conventions 2003 available at . With these resolutions, beginning on 1 January 2003, IERS Bulletins A and B will publish new products in addition to those already published. These products will include the celestial pole offsets X_obs-X_IAU2000A and Y_obs-Y_IAU2000A where X_obs and Y_obs are the observed X, Y coordinates of the Celestial Intermediate Pole in the Geocentric Celestial Reference System, and X_IAU2000A and Y_IAU2000A are the celestial pole coordinates provided by using the IAU2000A Precession-Nutation theory. It is expected that Celestial Pole offsets related to the IAU1980 Nutation Theory will continue to be published through 15 January 2006. The new celestial pole offsets related to the new IAU2000A Precession-Nutation theory will be produced in a separate data file as well as appended to to this file. ************************************************************************** Important Notice - IAU 2000 Resolution Compliancy Information **************************************************************************
