Comparison of MESS2 detection probabilities when removing a two-planet Keplerian model from the RV (left; assuming the candidate planet HD 113337 c is real) or only a one-planet Keplerian model (right; assuming only the confirmed planet HD 113337 b). This simulation was made in the case of the young age solution and for an inclination within 10–30°. The y-scale is zoomed-in on the 0–5 M_Jup range if compared to Fig. 8; the left plot corresponds to the same simulation as the top left plot of Fig. 8.
