Let us consider the data from Đuričković et al., 2011, and make a fit with two q-Gaussians (Fig. ). We can clearly see that the two q-Gaussians have different q-parameters, and consequently two different Tsallis entropic indexes (again, we can argue that the different entropic indexes are due to two different local environments with two different entropies). We can improve the fit, adding two further small components (Fig. ).
