Top view projection of the flux ropes in the full and inner current layer (resp. top and bottom panels), with the same color map as in Fig. 2. Numbers indicate the length in r_g along the current layer, with the outer edge of the inner white disk located at the current layer footpoint on the disk r_ft ∼ 2.5r_g. In the bottom panel, the white dashed lines locate the Y-ring. The white circle surrounds an X-point and delimits the region where we compute the transverse velocity profiles in Fig. 6.
