Outflow profiles along the reconnecting current sheet, the direction indicated by “∥” in Fig. B.1 at time t = 534.5 s. Blue solid line is for the charged velocity with values indicated at the left axis, red dashed line is for the decoupling velocity, with values indicated at the right axis. The location of 0 on the x-axis corresponds to the location the points marked by “X” along the current sheet in Fig. B.1.
