2D mass-weighted histograms of the logarithm of the plasma beta (β; top), total pressure (P; middle), and temperature (T; bottom) of the gas plotted against its density (n) for model T (left) and model R (right) at t = 500 Myr. The dots represent the mean values per density bin. The dashed white line in the top panel indicates the equipartition of thermal and magnetic pressure.
