4. Conclusion

We have presented the first spectroscopic orbits for ten red giants in the fields of seven open clusters, continuing the publication of the results of a long-term observing programme started in 1983 in the southern hemisphere. The total number of spectroscopic binaries amongst cluster red giants that can be reached with the present instrumentation remains appreciable, and observations of stars in the sample continues with the aim to accumulate a sufficient number of orbits for meaningful analysis of the orbital element distributions and their possible dependence on the ages and masses of the primary stars, or the masses and other dynamical properties of the parent clusters.
