LOS inclinations at log (τ) = −2 of four SOT/SP scans. The black contour lines indicate kG magnetic fields at log (τ) = −0.8. The colour bar applies to all panels, where blue represents positive polarity fields and red the negative polarity. The arrows indicate the direction of the azimuthal magnetic field component at log (τ) = −2 and the white line follows the PIL. The xy axes indicate the distance to disc centre. The three white boxes are identical to those in Fig. 1.
