Radial velocities of 35495 Hipparcos stars in a common system

Abstract

The Pulkovo Compilation of Radial Velocities (PCRV) catalogue has been produced to study stellar kinematics in the local spiral arm. The PCRV contains the mean weighted absolute radial velocities of 35495 Hipparcos stars of various spectral types and luminosity classes over the whole celestial sphere mainly within the radius of 500pc from the Sun. The median precision of the obtained radial velocities is 0.7kms-1. The results from 203 publications have been used in the catalogue. They are linked to the system of IAU standard stars or a list of secondary standards by means of the analysis of zero-point deviations and systematic dependences of the radial velocity differences ‘new observations minus standards’ on the radial velocity, colour index B-V, right ascension and declination.
