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.
UBVRI photometry of stars useful for checking equipment orientation stability Several sets of stars have been measured, equally spaced around the skyin right ascension, over a range in declination from -75 deg to +30 deg.The goal was to obtain a number of well-observed stars with qualityinternally consistent magnitudes and color indices. The stars wereneeded to check orientation effects of photometric equipment.
