Abstract:
The Pulkovo Compilation of Radial Velocities (PCRV) has been made to
study the stellar kinematics in the local spiral arm. The PCRV contains
weighted mean absolute radial velocities for 35495 Hipparcos stars of
various spectral types and luminosity classes over the entire celestial
sphere mainly within 500 pc of the Sun. The median accuracy of the
radial velocities obtained is 0.7km/s. Results from 203 publications
were used in the catalogue. Four of them were used to improve the radial
velocities of standard stars from the IAU list. The radial velocities of
155 standard stars turned out to be constant within 0.3km/s. These
stars were used to analyze 47768 mean radial velocities for 37200 stars
from 12 major publications (80% of all the data used). Zero-point
discrepancies and systematic dependences on radial velocity, B-V color
index, right ascension, and declination were found in radial velocity
differences of the form "publication minus IAU list of standards". These
discrepancies and dependences were approximated and taken into account
when calculating the weighted mean radial velocities. 1128 stars whose
independent radial-velocity determinations were available at least in
three of these publications and agreed within 3km/s were chosen as the
work list of secondary standards. Radial-velocity differences of the
form "publication minus list of secondary standards" were used by
analogy to correct the zero points and systematic dependences in the
radial velocities from 33 more publications (13% of the data used). In
addition, the radial velocities from 154 minor publications (7% of the
data used) pertaining to well-known instruments were used without any
corrections. Data are also available at:
