Maximum Msini value compatible with the RV measurements as a function of prospective orbital period. Upper panel: for G 264–012 RV curve. Lower panel: Gl 393 RV curve. From light to darker grey, detectability from original RV data (no modelling of planets or activity), data corrected for activity with GP, and data corrected from both, activity and planet signals. Symbols arethe same as in Fig. 15 with the planets in each of the two systems labelled only with b, c for G 264–012 and b for Gl 393.
