HD 22560

SANTIAGO 91, a right ascension catalogue of 3387 stars (equinox J2000). The positions in right ascension of 3387 stars belonging to the Santiago67 Catalogue, observed with the Repsold Meridian Circle at Cerro Calan,National Astronomical Observatory, during the period 1989 to 1994, aregiven. The average mean square error of a position, for the wholeCatalogue, is +/-0.009 s. The mean epoch of the catalogue is 1991.84.

Flux density and polarization observations of HIPPARCOS radio stars Simultaneous flux density measurements with the 64 m antenna of theMadrid Deep Space Communication Complex (DSCC) at a wavelength of 13.1cm and 3.6 cm, or of right and left circular polarization at 3.6 cm of agroup of radio stars from the Hipparcos Input Catalogue, are reported.The total number of stars observed is 33, while the number of starsdetected is 9. The polarization measurements of RS CVn systems are inagreement with a gyrosynchrotron emission mechanism. The observations ofLS I +61°303 confirm the period emission at 8.4 GHz.
