Red giants in open clusters. XIV. Mean radial velocities for 1309 stars and 166 open clusters. Mermilliod J.-C., Mayor M., Udry S. <Astron. Astrophys. 485, 303 (2008)> =2008A&A...485..303M
ADC_Keywords: Clusters, open ; Stars, giant ; Radial velocities Keywords: Galaxy: open clusters and associations: general - techniques: radial velocities - stars: late-type Abstract: We present the final catalogues of a long term observing program performed with the two Coravel spectrovelocimeters for red giants in open clusters. The main aims were to detect spectroscopic binaries and determine their orbital parameters, determine the membership, and compute mean velocities for the stars and open clusters. We computed weighted mean radial velocities for 1309 stars from 10517 individual observations, including the systemic radial velocities from spectroscopic orbits and for Cepheids. The final results are contained in three catalogues collecting 10517 individual radial velocities, mean radial velocities for 1309 red giants, and mean radial velocities for 166 open clusters, among which 57 are new determinations. We identify 891 members and 418 non-members. We discovered a total of 288 spectroscopic binaries, among which 57 were classified as non-members. In addition 27 stars were judged to be variable in radial velocities, all of them being red supergiants. File Summary:
