Fig. 3. Finite-size scaling is assessed using a software implementation with varying system size N.

a Exemplary avalanche size distributions $\mathcal{P}\left(s\right)$ follow a power law for any tested N (degree of input K_ext/N = 1/4). b As expected for critical systems, the cutoff s_cut scales with the system size. The scaling exponent is 1.6 ± 0.2.
