Observational Studies of Cepheids. VIII. Additional Radial Velocities of Cepheids and RR Lyrae Variables
Abstract
Radial velocities are given for 25 Cepheids and 8 RR Lyrae variables accessible from the McDonald Observatory. The accuracy of a single observation of unit weight is typically about + or - 4 km/s. These 480 velocities supplement those already published in this series.
