J/AN/328/889    Mean Radial Velocities of open clusters  (Kharchenko+, 2007)

Astrophysical supplements to the ASCC-2.5. Ia. Radial velocities of ∼55000 stars and mean radial velocities of 516 Galactic open clusters and associations. Kharchenko N.V., Scholz R.-D., Piskunov A.E., Roeser S., Schilbach E. <Astron. Nachrichten, 328, 889 (2007)> =2007AN....328..889K
ADC_Keywords: Clusters, open ; Associations, stellar ; Radial velocities 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. File Summary:
