Distribution of k₂ peak intensities in units of brightness temperature (panel a) and peak separation (panel b) for four snapshots in the MURaM-ChE simulation, which are separated by ≈2 min of simulation time. The presented data correspond to every second column in the x and y directions in the snapshots. The spectra were degraded before the peak-finding algorithm was applied. For comparison with Fig. 5, we chose the same limits for the axes.
