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.

The spiral structure of our Galaxy determined from H II regions
An attempt is made to establish a coherent scheme of the spiralstructure of the Galaxy on the basis of a study of H II regions andtheir exciting stars. The data used for this include the distances ofthe exciting stars, H-alpha radial velocities, and H109-alpha radialvelocities. A detailed model of galactic rotation is developed whichexhibits deviations from circular motion in certain sectors, thusallowing the stellar and kinematic distances to be matched correctly.The resulting spiral pattern is found to have two symmetrical pairs ofarms (four altogether) with a pitch angle of 12 deg. These areidentified as the Sagittarius-Carina Arm (the major arm or arm No. 1),the Scutum-Crux Arm (the intermediate arm or arm No. 2), the Norma Arm(the internal arm or arm No. 1'), and the Perseus Arm (the external armor arm No. 2'). It is concluded that the morphological type of theGalaxy is much closer to Sc than to Sb.
