Optical astrometry of Benchmark radio sources. II. Positions of 29 compact extragalactic radio sources with respect to the International Reference Stars catalogue.

COSTA E. and LOYOLA P.

Abstract (from CDS):

Optical positions, relative to the newly available International Reference Stars catalogue (IRS) have been obtained for the optical counterparts of 29 compact extragalactic radio sources south of δ≃+12deg ; Most of these sources have been selected by IAU Commission 24 to be used as Benchmark objects for the establishment of a high-precision radio/optical reference frame. Precision levels better than 0.2" in both coordinates were achieved. Comparisons with independent optical surveys and with VLBI radio positions available for these sources are presented. The use of the IRS catalogue is strongly supported.
