Top: CoRoT 2008 light curve (black crosses) with eclipses removed, showing three versions of our toy spot model (fit to the second half of the light curve only). Red solid line: T_spot = 3000 K, angular radius =55° (fraction of stellar surface covered =0.21) and latitude =70°. Green dotted line: T_spot = 2500 K, angular radius =50° (fraction of stellar surface covered =0.18) and latitude =70°. Blue dashed line: T_spot = 3250 K, angular radius =60° (fraction of stellar surface covered =0.25) and latitude =65°. Bottom: the red spot model with the period set to the binary orbital period (3.875 days).
