Cumulative distributions of flares per day with energies above a given threshold (log N(E >  E₀)). Dashed line indicates the full sample of flares (N_flares = 60); thin solid line is relative to the flares observed at planetary transits (N_flares = 47); thick solid line is relative to the flares observed at secondary transits (N_flares = 13). The lines refer to a linear fit of each sample in the form log N(E_X >  E₀)∝βlog E_X. The range with energies log E_X <  31.2 not used for the fit to the slopes is shaded in gray color.
