Visual multiples. IV. Radial velocities of 13 systems.
Abstract
120 radial velocities are given from spectra obtained with the Lick Observatory Mills spectrograph for 13 visual systems with periods of 2.6 to 26.4 years. The various identifications, the 1900 coordinates, the heliocentric Julian dates, the corrected radial velocities and the internal probable errors are tabulated.
