Maps of selected physical parameters (at log (τ) = 0) obtained from the inversion: a) temperature T; b) magnetic field strength B; c) magnetic field inclination γ; d) line-of-sight velocity v_LOS. The arrow in the temperature map points to the solar disk centre. Except for field inclination γ, thresholds have been used for minimum and maximum values of the colour bars. The extreme values returned by the inversion are 3853 to 7173 K for T, 10 to 4000 G for B, and −11.5 to 18.7  km s^-1 for v_LOS.
