Probability density functions (PDFs) of a) the intrinsic field strength, B, b) the magnetic filling factor, α and c) the inclination γ of the pixels having B_app,los in an interval of  ± 200 G around the peak value of B_app,los, for the quiet Sun (dotted curves) and the active region (solid curves) fields of view shown in Fig. 1. The vertical lines mark the mean values of the distributions.
