Variations of γ_LRF, B, and v_LOS along the cuts marked with white lines in Fig. 3. The solid and dashed lines show the atmospheric parameters and the continuum intensity, respectively. For display purposes, we changed the polarity of the field along the cut through the filaments of the regular penumbra and also increased γ_LRF by 10° and v_LOS by 1 km s^-1 there. The range of continuum intensities used to draw the dashed lines is the same for orphan and regular penumbrae.
