Averaged Stellar Radial Velocities

The data supplement the catalogs of Wilson (1953) <III/21> and Evans (1978) <III/47> with observations published through December 1980. There are new mean velocities for 6023 stars with new radial velocity data; more than 4500 of these stars are not in the earlier catalogs.

A weighting scheme was used to form the mean velocities with data from cross-correlation spectrometers given highest weight and low dispersion (less than 100 A/mm) spectra given lowest weight. No systematic zero-point corrections were made but observations were taken from the literature only if they were standardized to the IAU or Wilson (1953) systems.
