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.
| Low dispersion spectrophotometry of bright early-type stars
Intensity distributions for 79 stars of spectral types O9 to A3, plus anF3 star and 7 standard stars, are presented. The observations cover awavelength range from 3300 to 6000 A. The internal errors are discussed.Synthetic uby colors are obtained for all the stars observed, and arecompared with observed published data.
