Photometrie variations of the models shown in the top row of Fig. 5. The (J–H) versus (H–K) diagram (top left) and the light curves of the V (top right), J (bottom left), and K (bottom right) magnitudes for three periods in several epochs. The SDDO values are plotted in orange-red hues, and the SPL values are plotted in blue-ones. The model has the parameters Teff = 2600 K, log L = 4.0 L, mass 1.5 M, log(C–O) = 8.5, and a piston amplitude of 4 km s−1.
