Division A WG Multi-waveband Realisations of International Celestial Reference System

Description

To anticipate the evolution of the ICRS with the advent of realizations in different wavelength domains, initially with a radio version realized with VLBI and the optical version resulting from the ESA Gaia space astrometry mission. The WG will be also in charge to evaluate the alignment procedures between the two realizations and investigate the possible systematic differences between the radio and optical positions of the sources contributing to the realizations.
