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.

Photoelectric beta photometry of 118 stars with V in the range 14-15 and B - V not greater than 0.650 at the south galactic pole
Observations of a sample of 118 stars at the south galactic pole arepresented. Diagrams of instrumental vs standard beta values for thestandard stars may indicate that the transformation must be divided intotwo regions with slightly different slopes A and intercepts B. Thenarrow bandpass of the filter set employed has an FWHM of 27 A and iscentered at 4860 A. A radial velocity of 100 km/s will reduce thebeta-index of a sharp beta line with 0.005-0.010 m relative to a zerovelocity star. It is argued that the two transformations are a result ofslightly different bandwidths of the narrow-band filters used for theoriginal measurements of the present secondary standards and in thepresent observing run. The present narrow band's FWHM is smaller by 3 A.

Four-color UVBY and H-beta photometry of high-velocity and metal-poor stars. I - The catalogue of observations
A catalog of four-color uvby and H-beta photometry for 711 high-velocityand metal-poor stars is given. The selection of the stars and theobserving and reduction techniques used to obtain these data arediscussed. The photometry has been transformed closely onto the standarduvby-beta system. The errors of the data have been estimated using bothinternal and external comparisons. The data are uniform over the sky;that is, there are no significant north-south differences. For the largemajority of stars the mean errors of V, m1, c1, and beta are less than +or - 0.008 mag, and the error of b-y is less than + or - 0.005 mag.Values of V, b-y and beta and rough photometric classifications aregiven for 63 red and/or evolved stars that fall outside the range of thephotometric transformations.
