Top panel: histogram of the ratio between the semi-amplitudes of the orbital frequency and its second harmonic as obtained with the Monte Carlo simulations. The dashed vertical line indicates the observed value of the semi-amplitude ratio obtained via pre-whitening of the lightcurve averaged over the BRITE spacecraft orbit (A₁/A₂)_BRITE = 0.52 ± 0.05. Bottom panel: histogram of the difference between the two maxima of the simulated lightcurves. The observed value of this difference in the BRITE lightcurve (≃0.005 mag) is again shown by the dashed vertical line.
