The data are shown in a local current (LMN) coordinate with L = (0.88, −0.47, −0.01)GSE, M = (0.25, 0.50, −0.83)GSE and N = (0.39, 0.73, 0.56)GSE for Pulse1, and L = (−0.92, 0.05, 0.39)GSE, M = (−0.18, 0.82, −0.55)GSE, and N = (−0.35, −0.57, −0.74)GSE for Pulse2. a, g Magnetic field BLMN, with BM shifted by −40 nT for Pulse1 and −75 nT for Pulse2. b, h The total current density intensity. c, i Electron velocity Ve,LN. d, j Electron velocity VeM. e, k Perpendicular electric field E⊥LMN in the spacecraft frame. The perpendicular electric fields mean electric field component perpendicular to the local magnetic field. f, lJ • E′ = J • (E + Ve × B).
