Two-dimensional cut on the orbital plane of the smooth CD (solid gray line) at an intermediate orbital phase (ϕ = 0.28) showing the trajectories of multiple clumps. The light-gray shaded area gives a rough estimate of the thickness of the shocked two-wind region. The blue and yellow lines correspond to high-density and low-density clumps for stellar wind filling factors of f = 0.01 and f = 0.1, respectively. The clump radii when launched from the stellar surface are 0.1 R_* (solid) and 0.06 R_* (dashed). The colored shaded areas show the regions along the pulsar wind shock front within which the largest high-density (blue shaded area) and low-density (yellow shaded area) clumps can penetrate.
