Snapshots of sunspot scars and the field lines traced from rakes crossing through sunspot scars for both “Simulation 1” and “Simulation 2”. (a) Snapshot of vertical magnetic field on the plane z = 0.2 at t = 224 t_A in “Simulation 1”. The red dashed box shows the field of view in Fig. 8. (b) Magnetic field lines traced from two rakes at t = 224 t_A which cross through the two sunspot scars in the two polarities, respectively. The green tubes represent the CME flux rope field lines and the magenta tubes represent the inclined loops. The bottom plane shows the vertical magnetic field on the plane z = 0.2, same as that in panel a. The red filled contours show the footprints of QSLs (logQ > 3) on this plane. (c) Snapshot of vertical magnetic field on the plane z = 0.1 at t = 71 in “Simulation 2”. The red dashed box shows the field of view in Fig. 10. (d) Similar to panel b, but for that at t = 71 in “Simulation 2”. The bottom plane shows the vertical magnetic field on the plane z = 0.1, same as that in panel c. The green tubes, magenta tubes, and red filled contours have the same meanings as those in panel b.
