Five-halo mass estimation in the same format used in Figure 6. The mass centers were set to the convergence peaks. In some cases, where the distance between the two neighboring substructures is relatively small, the degeneracy is relatively high (the Pearson correlation coefficients are ρ = −0.535 for the NW_E−NW_W pair and ρ = −0.685 for the SE_N−SE_S pair).
