Relative power spectrum as a function of frequency for the set of stellar parameters B with |R_p| = 0.95 and different values of |R_g|. Gray vertical lines indicate the location of the local minima, green circles (red crosses) indicate the location of the resolved (unresolved) modes. The resolution criterion is described in Sect. 4.4. When the unresolved modes no longer corresponded to local maxima on the selected frequency grid, we used the resonance condition to determine their position.
