Left: changing longitudes of spots of TIC 326257590 in time. Red and blue circles result from time-series photometric modeling and eclipse mapping, respectively. The shade of the blue circles reflects the contrasts of the spots from eclipse mapping. Note that the x-axis of the figure covers one stellar circumference in longitude. Gray shading shows the longitudes scanned by the companion star. Right: light curve fitted by four spots. Black dots mark those eclipses that are mapped.
