Maps of the magnetic field vector (from left to right: magnetic field strength, B, inclination, γ, azimuth, φ) and LOS-velocity, υ_LOS, in the photosphere and upper chromosphere. The first three maps in every panel correspond to log τ = 0.0, log τ = −0.7 and log τ = −2.3 (SPINOR inversion of the Sii  and Cai  lines), and the fourth map refers to the upper chromosphere (HeLIx⁺ inversion of the Hei triplet). The box in the fourth map of panel b) represents the location for which details of various parameters are displayed in Fig. 4. Three arcs in panel d) show the locations of various parameters that are depicted in Figs. 6 and 7. An arrow in panel d) indicates the disk center direction.
