Abstract

Newly determined radial velocities are given for 15 standard velocity stars and 115 other bright stars south of the equator. Measurements from two-prism spectrograms (dispersion 90 A/mm at Hy) taken at the Newtonian focus of the -inch reflector are now entirely consistent with velocities determined elsewhere. Most of the present data are from the o-inch Cassegrain spectrograph (dispersion 36 A/mm at Hy). Nearly all the stars in this list are in the FK3 and N30 position catalogues, of the fifth or sixth visual magnitude. At least three spectrograms of each star have been measured. 34 new constant velocities are announced, and variability has been detected for the first time in Z3 other stars. Observations bave been resumed on 33 stars previously known to have variable velocity. A luminosity class on the revised Yerkes system is assigned where possible.
