The networks were each obtained from previous work as referenced. N, network size; K, degree; C, clustering coefficient; C_rand, clustering of an equivalent random network; C_latt, clustering of an equivalent lattice network; L, path length; L_rand, path length of an equivalent random network; σ and ω, small-worldness metrics.
