Comparison between the best-fit model for the primary RVs (black solid curve) computed with relation 1 for dataset 2. Cyan, blue, and violet filled symbols stand respectively for primary RVs from Hillwig et al. (2006) and our disentangling of the Aurélie and HEROS spectra. The orange, red, and maroon open symbols show the secondary RVs (not used in the fit) respectively from Hillwig et al. (2006), our Aurélie and HEROS data, whilst the dashed line illustrates the secondary RV solution inferred from the primary RV curve for a mass ratio q = m_p/m_s = 1.28 ± 0.03.
