Cross-dependence of the ten variables considered. Confirmed BWs (in red) and RBs (in green) are separately noted. For visualization reasons, no distinction is made between MSPs residing in globular clusters and those not, and the tMSPs are marked in green due to their behavior as RBs. The pulsars not yet assigned to any of these classes are shown in blue. The main diagonal shows the distribution for each variable. The panels with the shaded background show the pairs formed with P_B, M_C, and A₁, which best differentiate the BWs from the rest.
