Comparison of the Fourier spectra of light curves given in Fig. 7 (black curves) with Fourier spectrum of the theoretical light curve for N = 1 (red curves). The theoretical spectrum was scaled by a factor of 10^b taken from Table 1 accounting for N > 1. For the analysis we used the CoRoT light curves secured between JD 2456203 and 2456234 for HD 46150 and HD 46223 and between JD 2454748 and 2454783 for HD 46966.
