Four different test statistics as a function of the number of free parameters. Circles denote the traditional model while pluses denote the toy model. The filled (open) triangles mark the number of free parameters using only the frequencies with amplitude higher than 165 ppm for the traditional model (toy model). Top panel: AIC and BIC, where black open symbols correspond to the BIC and red filled symbols to the AIC. These statistics were calculated in respect to pulsation light curve. Middle panel: VR. Bottom panel: PR. All the insets show zoom-ins towards the areas concerning higher number of parameters.
