Notes. The first column shows the mode of the dynamical MCMC samples and the 68% credibility intervals as error bars. The medium and last columns show the nominal and stable best dynamical fits, respectively. All fits are fixed to be edge-on and coplanar (ib,c = 90 deg, Ωb = Ωc = 0 deg). We use the JD of the first RV observation, JD = 2 451 808.021, to set the epoch.
