A catalogue of QSOs and link stars for the HST link of the HIPPARCOS reference frame
A list of bright (less than 17 mag) southern QSOs and bright (less than11 mag) stars that may be suitable for the Hubble Space Telescope linkbetween the Hipparcos astrometric reference frame and the VLBIextragalactic frame is presented. The QSOs have been selected fromvarious lists of radio objects and identifications. The stars have beenselected from the Strasbourg (CDS) data base and from the PreliminarySecond Cape Photographic Catalog, and supplemented with stars measuredfrom the SERC IIIa-J Schmidt survey. These QSOs and stars have beenincluded in the Hipparcos and HST schedule of observations.

UBVRI photometry of FKSZ stars. II
The results of UBVRI photometry for 169 stars of the Faint FundamentalStars Catalog (Zverev, 1957) in the declination zone lambda of between-30 and -60 deg are presented. Observations were obtained between May1984 and February 1987 using the 50-cm ESO telescope at La Silla.Tabular data presented include the number of the star in the E-regions,the V magnitude, the (B-V), (U-B), (V-R), and (R-I) colors, and thespectral types.
