Results of the injection-recovery test assessing the detectability of a planetary signal in the dataset. The top panel shows the detection rate as a function of orbital period and semi-amplitude; the colors represent the percentage of successful detections. The red vertical lines indicate the boundaries of the habitable zone. The bottom panels display histograms of K_upper (left) and M_upper (right), representing the semi-amplitude threshold at which the detection rate reaches 100% and its corresponding minimum planetary mass.
