Results for the injection-recovery test in the RV residuals after subtracting the signal of Gl 725A b. The black zone is the parameter space of undetectable signals using a GLS periodogram, i.e with a FAP below 1%, whereas the white area is that for signals above 1%. The magenta star depicts the position of Gl 725A b, with a semi-amplitude of 1.67 m/s and an orbital period of 11.2 days. To help guide the eye, the light blue lines indicate the semi-amplitudes of 2 and 1 m/s.
