New subdwarfs. V. Radial velocities for 889 high-proper-motion stars measured with the Mount Wilson 100 inch reflector.
New radial velocities have been obtained from 2265 measurements of 889 high-proper-motion stars taken from the subdwarf candidate list of a previous paper. The observations were made with the Mount Wilson 100 in Hooker reflector coude spectrograph with a Reticon detector, giving an internal error of a single measurement of 4.7 km/s. From 88 stars in common with previously known subdwarfs; the external error of the data is 6.9 km/s per measurement, and the velocity system is shown to be on the system of the Wilson General Catalog to better than 1 km/s. Of the 878 stars with nonvariable velocities in the sample, 38 have radial velocities larger than 200 km/s, of which 22 are new. There is a correlation between radial velocity and reduced ultraviolet excess as expected from the previously known relations between space motion and chemical composition. The Stroemberg asymmetric drift is directly visible in the radial velocity and the proper-motion data separately as each is displayed as a function of galactic longitude.
