Amplitude spectra and excited frequencies of models A and models B (see Table 4). Observed frequencies are marked with triangles at the bottom and the frequencies attributed to pulsations are covered in a gray shaded area with the size of a fourth of the Rayleigh limit. Open triangles mark frequencies attributed to rotation. The excited frequencies of two chosen models are shown as red and blue hexagons. The inset shows a zoom in in the low frequency region of F2 and F4.
