Figure 7

The degree distribution of the network based on the PON R&C funding program is shown. The tail is fitted to a power-law function of the form \(P(k)=A k^{-\gamma}\) with \(A=4.156\pm0.375\) and \(\gamma=1.998\pm0.040\). The vertical grey line in part (a) shows the position of the cutoff (corresponding to the upper bound of the median interval) used to fit the tail. Part (b) shows the tail and the fitted line in Log-Log scale.
