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.
