Injection-and-recovery tests performed to check the detectability of extra planets in the system. We explored atotal of 663 different scenarios and five different phases each for a total of 3315 simulations. Then, each pixel evaluated about 20 scenarios, that is, 20 light curves with injected planets having different P_planet, R_planet, and T₀. Larger recovery rates are presented in yellow and green colours, while lower recovery rates are shown in blue and darker hues. Planets smaller than 1.5 R_⊕ would remain undetected for the full set of periods explored.
