Snapshot of the simulation. Panel a) Intensity in the continuum (first) band of the multi-group scheme; panel b) Vertical velocity at τ₅₀₀ = 1; panel c) Intensity in the low-chromospheric (fourth) band of the multi-group scheme; and panel d) Vertical magnetic field strength at τ₅₀₀ = 1. The maximum field strength has been saturated to better illustrate the salt-and-pepper field concentrations. The dashed line represents the slice shown in Figs. 2 and 8. Animation available online; the image represents t = 0 of the animation.
