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.

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.
