Intensity histograms over all pixels for the OH band data around 3118 Å. Top panel: the black line corresponds to the original 30 G MHD simulation, the blue line to the spatially degraded data, and the red line to the fully degraded simulation data. The green line displays the Sunrise observations. Bottom panel: influence of the MHD simulations’ mean flux density on the fully degraded OH intensity histogram. The black line shows a purely hydrodynamical simulation, i.e., without any magnetic field. The mean unsigned vertical flux density was 30 G for the histogram colored in red, 50 G for the blue line, and 200 G for the green line. rms contrasts are indicated in the text labels.
