Testing the relationship \((\kappa-1)\alpha_{G/P}=\alpha_{P}\). The data for the dates during 1 February 2019 to 9 February 2019 are excluded. (a) Exponents \(\alpha_{G/P}\) are those in Fig. 9(a) for the directed networks and Fig. 9(c) for the undirected networks, while exponents \(\alpha_{P}\) are those in Fig. 6(a) for the directed networks and Fig. 6(c) for the undirected networks. (b) Exponents \(\alpha_{G/P}\) are those in Fig. 9(b) for the directed networks and Fig. 9(d) for the undirected networks, while exponents \(\alpha_{P}\) are those in Fig. 6(b) for the directed networks and Fig. 6(d) for the undirected networks
