Distributions of inclination of MBPs obtained from the proposed geometric method, γ_p (see main text). The (black) hashed, (blue) shaded and (red; dot-dashed) outlined histograms represent the distributions of γ_p obtained from combinations of two atmospheric layers of the IMaX/continuum-IMaX/line-core, the IMaX/continuum-SuFI/Ca ii H, and the IMaX Stokes V images made in the inner and outer flanks of the line, respectively. All histograms are normalised to their maximum values. The vertical dashed lines indicate mean values of the histograms.
