Flux rope and associated current density distribution for AR 11429, derived from the CFIT N solution. (a) Dashed lines indicate the locations of vertical slices perpendicular to the main PIL considered for analysis. The lower boundary shows B_z(x, y, 0) and the main PIL, similar to previous figures. (b) Current density in a vertical slice perpendicular to the upper section of the PIL (black dashed line in panel (a)). The field lines passing through the vertical slice are colored by ∣J_CFIT(x, y, z)∣, sampled along the line. The normal current density in the slice, J_n, is positive for currents flowing in the direction of the normal vector to the plane. (c) Similar to panel (b) but for a vertical slice perpendicular to the lower section of the PIL (magenta dashed line in panel (a)).
