1D parameters along the slit crossing through the sunspot scar (dashed lines in Fig. 4). From the top to the bottom, they are continuum intensity (panel a), total magnetic field strength (|B|; panel b), vertical magnetic field strength (B_z; panel b), horizontal magnetic field strength (B_h; panel b), inclination angle (panel c), and vertical current density (J_z; panel d). The time of sub-panels in each column is shown in the first row of them. The black vertical dashed line in each column marks the dip of B_z in the sunspot scar, which is regarded as the sunspot scar center. The gray dashed lines in each column show the range of the two peaks in J_z which are at two sides of the sunspot scar, representing the edges of the sunspot scar. The black horizontal dashed line in panel d marks the value where the current density equals zero.
