TESS transit coverage map for the candidate planet TOI-4342 d. Each pixel corresponds to a combination of orbital period (P) and time of conjunction (T₀). The color scale indicates the number of possible transits that fall within the TESS observation windows. The dashed white lines mark the median values of P_d and T_{0, d} derived from the RV analysis, while the shaded white bands show the corresponding 1 σ uncertainties of P_d. The regions in white colors correspond to parameter combinations for which not covered by TESS observations.
