Reduction of compiled catalogue in the selected extragalactic radio source (ERS) fields
Abstract
The work is devoted to a problem of deriving of the compiled catalogue of the positions of reference stars 12-15m in the ICRF ERS vicinities for -20° < δ < 90°. This research is made on the basis of the international Joint Project "Improvement of the link between optical and radio reference frames" collaboration. Nikolaev Astronomical Observatory, Astronomical Observatory of Kyiv University, Main Astronomical Observatory of the Russian Academy of Sciences and Astronomical Institute of the Romanian Academy take part in the compilation of the catalogue. The catalogue is created on the basis of both original astrometric materials of these observatories and other known catalogues of stars in the ICRF ERS vicinities. It is planned to receive the first version of the catalogue in 2003 year.
