Dependence of ρ_I on the jumping probability p with the “squares”, “circles”, “uptriangles”, and “downtriangles” being , , , and , respectively, where panel (a) represents the case of β₁ = 0.003 > β_1c0 and β₂ = 0.005 > β_2c0, (b) the case of β₁ = 0.003 > β_1c0 and β₂ = 0.003 < β_2c0, (c) the case of β₁ = 0.0014 < β_1c0 and β₂ = 0.005 > β_2c0, and (d) the case of β₁ = 0.0014 < β_1c0 and β₂ = 0.003 < β_2c0 but with β₂ > β_1c0. The results are averaged over 1000 realizations.
