Abstract

Metallicities and distances have been determined from Vilnius photometry for an in situ sample of nearly 650 stars in eight proper-motion fields at,high Galactic latitudes. For half of these stars, radial velocities have been measured with the CORAVEL spectrometer, which allowed us to derive spatial velocities and-Galactic orbits. In this contribution we present a status report on our-results for the stellar content of the Galactic disk,with emphasis given to specific aspects of distinguishing the thick-disk stars from.-the old thin-disk population.
