Figure 11.

Left panel: largest connected component (LCC) fraction $N_{\mathit{LCC}}^{\prime }/N^{\prime }$ vs average degree $⟨k⟩$ in the sampled subnetworks of the US power grid. Each point corresponds to a fixed subsampling size $N^{\prime }$: the ordinates represent the mean values obtained from $M=100$ realizations and the error bars are the standard deviations of the respective distributions. The inset shows the behavior of the same quantity in the ER network ensemble. Right panel: power-law fit, on a log-log scale, of the LCC fraction for $⟨k⟩>1$, yielding $N_{\mathit{LCC}}^{\prime }/N^{\prime }-(N_{\mathit{LCC}}^{\prime }/N^{\prime }){|}_{⟨k⟩=1}\sim {(⟨k⟩-1)}^{7.0\pm 0.1}$.
