Histograms of intensity for all pixels in all snapshots for a given ⟨ B_z ⟩ shown in the legend. The field-free mean intensities (averaged over all field-free snapshots) are marked by grey vertical lines with the minimum and maximum values of the mean intensities of the individual field-free snapshots indicated by black horizontal bars. Also shown are histograms and the range of snapshot-averaged intensities for simulations with ⟨ B_z ⟩ of 100 G (purple), 300 G (cyan) and 500 G (red). The histograms are shown at two different limb positions: μ = 1.0 (solid curves) and μ = 0.5 (dashed curves). Panel a shows histograms for a wavelength of 214.5 nm with a bin width of 5 × 10^-11 W m^-2 sr^-1 Hz^-1. Panels b–d show wavelengths of 387, 601 and 1597.5 nm respectively, with a bin width of 1 × 10^-9 W m^-2 sr^-1 Hz^-1. Both, the x and the y scale vary between graphs.
