Example transit light curves for the three test cases simulated in this work, (a) An Earth-like planet (Sect. 4.2) showing a shallow transit depth (~100 ppm). We selected Transit #10 from a median system configuration with P_m ≈ 6 d and P_b ≈ 98 d (system ID: simu 2). (b) A warm Jupiter (Sect. 4.3) showing a deep transit with short duration. We selected Transit #17 from a representative system with P_m ≈ 3 d and P_b ≈ 51 d (system ID: simu 20). (c) A cold Jupiter (Sect. 4.4) exhibiting a significantly wider transit duration due to the wider orbit. We selected Transit #5 from a system with P_m ≈ 5 d and P_b ≈ 246 d (system ID: simu 22). The solid black line represents the total flux model, while the gray points show the simulated data with noise. The approximate number of observable transits (N_tr) for each scenario over the 4-year mission baseline is indicated in each panel.
