Abstract
We present a catalogue containing 1446 individual radial velocity valu es for 79 field Cepheids and three Cepheids in globular clusters, and 32 averaged radial velocities of the Cepheid alpha UMi derived from 10 0 individual velocity values. The catalogue is based on observations m ade in 1987-1991 with the correlation spectrometer designed by A. A. T okovinin. We include a table of gamma-velocities for 30 Cepheid with s ufficiently good coverage of V(r) curves. Radial velocities of several Cepheids have been measured for the first time. Thus, our radial velo city observations of CE Cas A and CF Cas, photometric members of the o pen cluster NGC 7790, enabled us to estimate the radial velocity of th e cluster (-78.0 km/s). For individual stars remarks are given, mainly concerning manifestations of Cepheid spectral binarity.
