Heat maps of ΔB_z = B_z − B_z(t = 0) (first row), E_∥ (second row), J_z (third row), and (fourth row) for the HVM (left column, ), HVLF (central column, ), and iPIC (right column, ) simulations. These times are chosen by fixing the value of the reconnected magnetic flux. This value is in the middle of the super-exponential phase. The plot is zoomed-in around the main X point. The is the rms value of E_∥ in the shown region.
