Power Spectral Densities (PSD) of the time-series of the species in the p53 model for the unperturbed parameter regime (black), when b x is perturbed by +20% (blue) as well as when b y is perturbed by +20% (yellow). The value and the position of the prominent peak of the PSD are related with the amplitude and the frequency of the species oscillations. The visual comparison between the averaged PSDs suggests that the spectral properties are more sensitive to b x than to b y .
