Orbital RV curves after removal of the long-term cyclic changes. Top: residuals from a smoothing by Vondrák (1977) method, using the smoothing parameter ε = 1.0 s ×  10−15. Middle: residuals from the local ‘triple-star’ solutions (see the text for details). Bottom: residuals for the RVs of the Hα emission wings also based on the ‘triple-star’ local solutions. Data from Feros, Elodie and DAO spectra are shown by blue circles, OND by red, Trieste by magenta, and BeSS by green circles.
