V/67                An astrometric catalogue of radio stars  (Hering+ 1990)

An astrometric catalogue of radio stars Hering R., Walter H.G. <Bull. Inf. CDS 38, 209 (1990)> =1990BICDS..38..209H =1990A&AS...86..357W
ADC_Keywords: Stars, radio ; Positional data ; Proper motions ; Description: Astrometric data in the optical and radio spectral ranges have been assembled for some 200 radio stars which are considered promising objects for linkage of optical and radio frames. Astrophysical data have been added to support observational programmes and data analysis. The full catalogue, in its original form as the file "catalog.ori", contains explanations, followed by the data for each star organised as paragraphs (blocks of lines separated by a blank line). Each paragraph representing a radio star in this catalog consists of 17 categories of stellar parameters; each category may contain zero, one, or more records. The positions, proper motions and parallaxes in the optical and radio domains are assigned categories 1 to 7; categories 8 to 13 deal with photometrical and spectroscopical parameters, duplicity and variability descriptions; and categories 14 to 17 contain references to finding charts and radio maps, as well as remarks about observation priorities. A detailed description of these categories are present at the beginning of the "catalog.ori" file. File Summary:

History: The catalogue was received at CDS in 1990 from the authors. The files "stars.dat" and "refs.dat" were generated in February 2002 at CDS (Francois Ochsenbein) as excerpts from the file "catalog.ori", and this documentation was generated.
