The resulting detectability map from the injection-and-retrieval experiment. Each pixel corresponds to ten of the 3000 different scenarios, that is, 10 light curves with injected planets having different P_planet, R_planet, and T₀. Larger recovery rates are presented in yellow and green colors, while lower recovery rates are shown in blue and darker hues. The red dot refers to TOI-4438 b, which has a recovery rate of 100%, highlighting the ease of detecting mini-Neptunes in this TESS data set with orbital periods shorter than 15 d.
