Improving the Reference Frame by Radio–and Optical Astrometry of Radio Stars
Published online by Cambridge University Press: 12 April 2016
Abstract
A longterm program of precise radio – and optical astrometry of selected radio stars has been conducted in the last decade by our observatories using the VLA and astrographs on both hemispheres. Positions of 54 stars north of −26 deg. declination including 6 MASER stars have been obtained. The program status and some results from the southern hemisphere are reported.
