Left panel: TESS observations of TIC 326257590 made between August 2019 and January 2023, with the primary eclipses marked with red. Six individual light curves are marked with different colors and are phased with the orbital period in the right panel, showing the variability of the light curves due to spots at different epochs. The dash-dotted red line shows the approximate ellipsoidal light variations shifted to the most dense part of the observations for comparison.
