Hourly binned photometry of GJ 207.1 from TESS sectors 6 (left) and 32 (right), phase folded to the orbital period. We show the best fit, described by Eq. (4), as a green solid line. The activity-induced variability is shown as a dash-dotted red line, while the magenta dotted line and the dashed blue line describe the ellipsoidal effect and the Doppler beaming, respectively. Bottom panels: residuals of the best fit.
