Radial Velocities of Population II Stars. II.
A program for radial velocity measurements of Population II stars wasstarted in 1988 and was carried out during six observing runs. Theprogram includes metal-deficient stars, components of Population IIvisual binaries or common proper motion stars, suspected radial velocityvariables and the Population II stars from the Hipparcos program. Themeasurements were made with the 1 meter reflector at the MaidanakObservatory in Uzbekistan. The average error of a single measurement isabout 0.6 km/s, but for stars at 13 mag or for extremely metal-deficientstars the error is about 2.5 km/s. The catalog contains 621 measurementsfor 164 stars.

Radial velocities of Population II stars. I
Radial velocity measurements are presented for 81 Population II stars.The sample comprises components of metal-poor binary stars,spectroscopic binary candidates, high latitude supergiants,metal-deficient stars with spectroscopic determinations of Fe/H,HIPPARCOS program stars, and some other stars of metal-poor population.The radial velocity measurements were made in February 1988 with aphotoelectric stellar velocimeter.
