Simulated X-ray luminosity, L_X, increases monotonically with increasing magnetospheric radius, R_m, and saturates at R_m ≳ R_LC. We attribute this to the wind luminosity intercepted by the disk and the wind dissipated fraction both increasing with increasing R_m and saturating once R_m is outside the light cylinder (Appendix A). Data from the sim-d100 model are shown in light blue, data from the sim-d36 model are shown in black, and the average X-ray luminosity of the isolated pulsar model is indicated with the short horizontal line. Symbols follow the same legend as in Figure 2. The red curve is plotted to guide the eye across the correlation. The few accretion column events generally overshoot the observed X-ray luminosity (see the last paragraph of Section 4.1).
