Abstract:
Radio stars play a key role in establishing the link between optical
reference frames and the conventional celestial reference frame based
on extragalactic radio sources. The relevant astrometric,
astrophysical and radio quantities are compiled of 66 cardinal radio
stars currently suited to frame connection and main tenance of the
link. The catalogue entries are supplied with ample bibliographical
codes and annotations for easy data retrieval.
