Photoelectric radial velocities, Paper XVII The orbits of 30 spectroscopic binaries in the southern Clube Selected Areas
Three of the six southern Clube Areas that were mainly observed at theEuropean Southern Observatory and whose principal results are given inPaper XVI are marginally observable from Haute-Provence. Additionalmeasurements obtained on several observing runs there enabled orbits tobe determined (in most cases rather poorly, owing to the paucity ofdata) for 30 of the newly discovered spectroscopic-binary systems; theyare presented in this paper. One object, HD 33978, seems to be of suchsignificance that special efforts have been made, largely by Drs J.Andersen and H. Lindgren, to obtain additional radial-velocitymeasurements. That system is shown to be a double-lined binary with aperiod of only 10.67 d despite one of its components being a late-typegiant. The giant star has a projected rotational velocity of almost 40km s-1 it could be expected to exhibit RS CVn-typephotometric variations, which have not yet been observed, in addition tothe `ellipsoidal variation', discovered by Hipparcos, which occasionedits designation as VV Lep.

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.
