The panels in the upper row show the continuum intensity at 630 nm wavelength (upper left), a gray-scale image (``magnetogram'', saturated at $\pm 10~$ G, black and white colour indicating the two polarities) of the (signed) vertical field component on the surface $\tau _{630}=10^{-2}$ , roughly corresponding to the formation height of the spectral line used for the observations (upper middle), and the unsigned horizontal field strength (upper right), black colour in this panel representing a very weak field and white colour indicating the saturation level of 10 G. The two panels in the lower row show gray-scale images of the logarithm of the horizontal field strength (black colour indicating fields below 1 G) for vertical cuts through the simulation box along a horizontal line at y=1.5 Mm ( left) and y=3 Mm ( right), respectively, in the upper panels. The level of $\tau _{630}=1$ is roughly at a height of 0.9 Mm, the level of $\tau _{630}=10^{-2}$ at 1.2 Mm.

In the optical depth interval $-2 < \log(\tau_{630}) < -1$ (relevant for the formation of the FeI lines used in the Hinode SP), the ratio is roughly in the range 4-6.

The dashed curve shows the energy spectrum based on the vertical field component, while the solid curve gives the arithmetic mean of the spectra for the two horizontal field components. For low wavenumbers, the energy in the horizontal field clearly dominates.
