Notes. The 1-σ error-bars on the parameters are provided by LOSP, except for the orbital period whose uncertainty is determined on the basis of the natural width of the peaks in the Fourier power spectrum. The orbital solution of HD 193443 was computed assuming that the uncertainties on the secondary RVs are three times as large as for the primary.
