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 66 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.

Note (1):
    New        : New mean radial velocity (MRV) for the cluster
    None       : No member found, and no MRV
    Confirmed  : Present MRV confirms the literature value
    Improved   : Present MRV better that that existing in the literature
    Updated    : Present MRV replaces the one previously published
    Membership : Red-giant membership not confirmed, but probbly member
