An Astrometric Catalogue of Radio Stars

Abstract

The first part is presented of a radio star catalog encompassing 186 objects whose selection was guided by the priority criteria of the Hipparchos Input Catalogue Consortium. Since these criteria are well suited to the need for linkage of ground-based optical systems to radio reference frames, this first selection is also considered a suitable base for the catalog. Seventeen categories of stellar parameters are furnished for each of the stars, including optical and radio positions, optical and radio parallax, radial velocity, type of variability, and optical structure.
