Detection-limit grid of 2.4 × 10⁶ random planetary-sine signals of RV amplitude 0.1–5 m s⁻¹ and of period 1–1000 d. The grid is formed by 200 × 200 log-spaced bins. Stellar rotation complicates detection considerably for orbital periods near P_rot (solid blue line) and P_rot/2 (dashed blue line). We display our best-model solutions (d4; black error bars) alongside solutions of Neptune- and Earth-mass planets (dotted black lines). Reported uncertainties reflect the 16^th and the 84^th percentiles.
