Spectroscopic Binaries in the Open Cluster Trumpler 16 Revisited

We have recalculated the orbits of 3 binary systems, members of the open cluster Trumpler 16 in the Carina region. We have added new observations to those available in the literature. Also, we have also tried to find the orbital periods for two suspected binary systems in the same cluster. We have improved considerably the precision of some of the orbital parameters.
