SPINOR 2D inverted parameters at three photospheric layers. From left to right: log (τ) = −2.0, −0.8 and 0. From top to bottom: temperature T (K); magnetic field intensity B (G); line-of-sight velocity v_LOS (km s^-1); and the micro-turbulence velocity v_MIC (km s^-1). In all maps, the black thick contour encloses a penumbral region where a counter EF is observed. The white arrows on the temperature maps point towards the disk center. Black crosses on the B maps indicate the location of a local maximum of the umbral field strength at log (τ) = 0. Also, the color-bar scale is sometimes saturated.
