cds-question@unistra.frastrometryradio-sourcesinterferometryproper-motionsWe have used the Very Large Array, linked with the Pie Town Very Long Baseline Array antenna, to determine astrometric positions of 46 radio stars in the International Celestial Reference Frame (ICRF). Positions were obtained in the ICRF directly through phase referencing of the stars to nearby ICRF quasars whose positions are accurate at the 0.25mas level. Radio star positions are estimated to be accurate at the 10mas level, with position errors approaching a few milliarcseconds for some of the stars observed. Our measured positions were combined with previous measurements taken from as early as 1978 to obtain proper-motion estimates for all 46 stars with average uncertainties of ~1.7mas/yr.2007AJ....133..906Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/906CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/251 : VLBI International Celestial Reference Frame (ICRF) (Ma+ 1997)J/AJ/127/3587 : VLBI ICRF.
