Description:
We have used the 2nd version of the Catalogue of Radial Velocities
with Astrometric Data (CRVAD-2, Cat. III/254) for a new
determination of mean RVs of 363 open clusters and stellar
associations considering their defined members from proper motions and
photometry in the All-Sky Compiled Catalogue of 2.5 Million Stars
(ASCC-2.5, Cat. I/280). For 330 clusters and associations we
compiled previously published RVs from the literature, critically
reviewed and partly revised them. The resulting Catalogue of Radial
Velocities of Open Clusters and Associations (CRVOCA) provides RVs for
516 open clusters and stellar associations in the Solar neighbourhood.
Objects in the catalogue are sorted in the order of increasing right
ascension J2000.
