cds-question@unistra.fropen-star-clustersspectroscopic-binary-starsradial-velocityWe present new orbits for ten (single-lined) spectroscopic binaries in seven open clusters: NGC 2489, 2567, 3033, 5822, 6134, 6664 and IC 2488 based on 243 individual radial velocities obtained with the southern CORAVEL scanner. The orbital periods range from 98.5 to 3566 days. The shortest-period orbit is circular, as expected. Seven of the binaries are confirmed cluster members, one is a possible member, and two are clearly non-members. Maximum masses from photometric separation and minimum masses from the spectroscopic orbits define the mass of the secondaries within an interval of M_max_-M_min_=0.5M_{sun}_. NGC 6664 #54 seems to have a rather massive secondary (M>3M_{sun}_), but the UBV colours appear normal for a luminous red giant, while significantly bluer (B-V) and (U-B) colours would be expected. It could be a triple system, the secondary being itself a short period binary. This paper brings the number of orbits published in this programme to 53, 45 of which are confirmed red-giant cluster members and 8 are non-members1997A&A...319..481Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/319/481CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/299/53 : Part IV.
