Abstract
A total of nearly 1500 radial-velocity observations of more than 500 7 m –10 m stars has been made with a photoelectric spectrometer. Nearly every star has been observed in more than one season. The standard errors of individual observations are mostly in the range 1.0 to 1.5 km/s. Eighty-five per cent of the mean velocities have standard errors of 1.0 km/s or better. The number of stars for which such good velocities are available is thereby increased by a third; almost all the good velocities known hitherto refer to naked-eye stars. A comparison of the photoelectric results with the 41 b -quality velocities available for the same stars in the Radial Velocity Catalogue shows the standard error of the catalogue velocities to be 3.2 ± 0.4 km/s.Keywords
