===================================================================== NOTICE TO USERS _____________________________________________________________________ Resolutions passed at the 24th General Assembly of the International Astronomical Union recommend the implementation of new procedures concerning the transformation between the celestial and terrestrial reference systems. To comply with these resolutions, BULLETIN B, giving EOPs with a two months delay, will be duplicated from March 2003 onwards to give dX = X_obs - X_IAU2000A and dY = Y_obs - Y_IAU2000A in the new formulation in addition to the current issue containing (dpsi, deps)_1980. New files containing dX and dY, listed in the same format, will be available at the following Web/ftp sites: - Web: http://hpiers.obspm.fr/eoppc/bul/bulb/bulletinb_IAU2000.Nb (Nb:issue Number) - anonymous ftp: hpiers.obspm.fr files : /iers/bul/bulb/bulletinb_IAU2000.Nb ===================================================================== BULLETIN B 179 3 January 2003 Contents are described in the Explanatory Supplement available at http://hpiers.obspm.fr/eop-pc/ 1 - EARTH ORIENTATION PARAMETERS (IERS evaluation).
