Fig. 1


Light curves of our five target stars displaying the flux normalized to the respective maximum value vs. the time as labelled. Errorbars are within the size of the symbols and indicate the standard error of each point that is an average of individual CoRoT measurements along two consecutive satellite orbits (open black circles). Filled orange circles indicate the segment of the light curve fitted to find the spot rotation periods (see Sect. 3).
