Time-series spot modeling of the K2 data free from the eclipses, ellipsoidal light variations, and any other effects of binarity, i.e., showing the spot modulations only. In the upper panel the K2 light curve is plotted in magenta, together with the almost identical fit from our 4-spot model (blue line). The residuals from the 4-spot model are plotted in the lower panel (black curve), while the deviations of the 2-spot model from the data is plotted in red.
