Mixing of the different materials in the plerionic supernova remnant 80 kyr after the supernova explosion. The line colours distinguish the mixing for the main-sequence (orange), red supergiant (red), Wolf-Rayet (magenta) wind materials, supernova ejecta (cyan), and pulsar wind (black), respectively, displayed as a function of the angle, θ_mag, between the ISM magnetic field and the rotation axis of the pulsar.
