Spatial distribution of the SNR radius. Histogram of the RS (blue), CD (orange), BW (green) radius both without (a) and with (c) turbulence obtained 450 yr after SN explosion (simulations displayed in Fig. 1). To compensate for the spatial variation of the BW radius appearing in the turbulent case, the RS and CD radii are normalised using their respective BW radius for each solid angle both without (b) and with (d) turbulence.
