Radial velocities of ring-shaped galaxies
Abstract
Radial velocities are determined for 44 objects on Kostyuk's (1975) list of galaxies with outer ring structure. A 6-m telescope is used with an internal rms error of 63 km/s. For 12 cases the radial velocity is derived from several spectrograms to compute an external error of measure of 41 km/s.
