Caption: Figure 15.

Upper panels: same as Figure 14 but for TIC 258507555. Large sections of the lightcurve are dominated by systematics, especially in Sector 19 when the target is close to the detector edge. Lower panel: same as Figure 8 but for TIC 258507555. There are no indications for significant ETVs on PA. Here, Gaia measured an outer period Pout ≈ 277 days and eccentricity eout ≈ 0.1. The ETVs in TESS are too sparse to estimate the orbital period.
