The accuracy of the orbital solution has been substantially improved after the observed RV changes were properly prewhitened for the short-term oscillations. The analysis of RV scatter gives some indication of a sharp increase of this scatter when the stars are approaching periastron. Since this could be a signature of forced oscillations.
