A catalogue of data on galactic cepheids =============================================================================== Berdnikov L.N., Rastorguev A.S., Dambis A.K., Glushkova E.V. =============================================================================== ADC_Keywords: Cepheids; Photometry; Kinematics; Distance scale Abstract: This catalog includes all available kinematical data on 440 galactic cepheids with the distances calculated with the period-luminosity relations of Berdnikov et al. (Astron. Lett., 1996, V.22, P.838). Their radial velocities were taken from the literature, proper motions and coordinates mostly from HIPPARCOS and TYCO-2 catalogs.
