Distribution of PPCs. Distribution of PPC for physically connected nodes (blue), disconnected nodes (red) and all pairs of nodes (green) at different coupling strength and for different network topologies. The data is averaged over five different initial configurations. At K = 0.010 a bimodal distribution of PPCs for all pairs of nodes is observed in all the network topologies. The threshold used to reconstruct physical network can be around 0.130 by which two modes of the distribution are well separated.
