For Case 0 at the reconnection site ﹩x=22.8{d}_{i}﹩. The z profile of (a) the initial magnetic flux ﹩{\psi }_{0}={B}_{0}{\delta }_{0}\mathrm{ln}\left[\cosh \left(z/{\delta }_{0}\right)\right]﹩ and the z profiles of (b) perturbed magnetic flux ﹩{\psi }_{1}=\psi -{\psi }_{0}﹩, (c) out-of-plane ion current density j_iy, and (d) out-of-plane electron current density j_ey at representative moments. The magnetic flux is in units of ﹩{B}_{0}{d}_{i}﹩, and the current densities are in units of ﹩{{en}}_{0}{V}_{{\rm{A}}}﹩.
