Caption: Figure 2.
Multinight LCOGT 1.0 m ground-based follow-up lightcurve. The differential lightcurve was extracted using a common set of 22 reference stars and was normalized over the full dataset. No lightcurve detrending was applied. Gray symbols show the unbinned data. Black symbols show the data in 8 minute bins. The vertical red dashed line shows the nominal midtransit time based on the updated ephemeris from the global fit (Section 3), which is based on the single TESS transit detection and all available radial velocities. The blue shaded region indicates the midtransit time 1σ uncertainty window. The apparent 6 ppt in-transit detection is just outside the 1σ window. The bounds on the orbital period based on the TESS single transit, RVs, and the apparent LCOGT in-transit detection are P = 131.125 ± 0.012 days.
