Bessho, NaokiChen, Li-JenWang, ShanHesse, MichaelNormalization: position x and z by d_i, B field by B_0, E field by B_0v_A/c. In file names for fields, ?? represents a kind of field, bx, ey, ez, or ay. XX represents time, 21 or 25, indicating t=21.1 or 25.3, respectively. Field profile in z (??avXX.txt): field profile, averaged in the x direction (between -5+i and 5+i, 11 points, where i is the x grid of the X-line), 1st column: z position, 2nd column: field. 2-D field contour (??XX.txt): 1st column: z position, 2nd column: x position, 3rd column: field. In file names for reduced electron VDFs: ffXX-yx-zYY.txt, where XX represents time, 21 or 25 (t=21.1 or 25.3), and YY represents the distance from z=0 (for example, z0.3 means the VDF at z=0.3. z0 represents the VDF at z=0 ). VDF in vy-vx plane (ffXX-yx-zYY.txt): 1st column: vy, 2nd column: vx, 3rd column: VDF. VDF in vy-vz plane (ffXX-yz-zYY.txt): 1st column: vy, 2nd column: vz, 3rd column: VDF.2-dimensional particle-in-cell simulation data for a paper, "Effect of the reconnection electric field on electron distribution functions in the diffusion region of magnetotail reconnection".particle-in-cell simulationmagnetic reconnectionDataset
