Achieved detection limits for our sample versus main stellar parameters. For all panels, each black dot represents the detection limit for one target. All targets are displayed except for stars with detected GP companions. Left: mean detection limit in the range 1–10 days; middle: mean detection limit in the range 10–100 days; right: mean detection limit in the range 100–1000 days. Top: detection limits vs. B−V; middle top: vs. vsini; middle bottom: vs. M_⋆; bottom: in histograms.
