Catalog of mean stellar radial velocities (catalog on magnetic tape) A catalog of the mean radial velocities for 6451 Galactic stars isdescribed, which supplements the General Catalogs of Wilson (1953) andEvans (1978) with published observations up to December, 1980. Onlyobservations with adequate spectral resolution and standardized to theIAU or Wilson velocity systems are included in the catalog. The accuracyand sources of the data, and the weighting system used in constructingthe catalog are discussed. A sample section of the catalog is presentedand explained.
