Histograms for the horizontal cross-sections displayed in Fig. 1 for the same model snapshot (red) and for snapshots stretching over the second half of the simulation (grey/black). The columns are in the same order as in Fig. 1: gas temperature, logarithm gas pressure, and the product of the absolute velocity and the sign of the vertical velocity component, all on planes of equal optical depth. The rows are, from top to bottom: convection zone (log τ_Ross = 6.0), photosphere (log τ_Ross = 0.0), and chromosphere (log τ_Ross = − 6.0). The solid vertical lines mark the average values, whereas the dashed lines mark the average plus/minus one standard deviation.
