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

An astrometric catalogue of radio stars

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.
