Fine structures inside the current sheet (CS) at t = 9.6. a) Current distribution on the cut y = 0; magnetic field lines passing through points uniformly distributed on the z-axis (black lines) and outside the CS (blue lines). The inserts on the left side give the variation of physical quantities along the line marked on this panel. A red point PX and a red box are marked for the evaluation of reconnection rates. b) Distributions of plasma velocity (arrows) in the vicinity of the CS. c) Distribution of parallel electric field .
