Log probabilities for individual aliases below 100 d from MonoTools analysis. Dark red bars show aliases ruled out by CHEOPS non-detections. Light red bars show aliases ruled out by the initial CHEOPS transit (at t₃ = 2460254.82; also identical to the alias constraints from the additional TESS transit at t₅ = 2460619.47). Light blue bars show potential aliases after the third transit. The dark blue bar (P_b ∼ 52 d) shows the only other remaining alias after the second CHEOPS transit detection (at t₄ = 2460306.92), and the green bar shows the true period confirmed by the third CHEOPS transit observation (at t₆ = 2460645.53). Only solutions with P < 100 d are shown.
