title: Dataset for Electron heating associated with magnetic reconnection in foreshock waves: particle-in-cell simulation analysis

description: The dataset is the simulation data included in the paper of "Electron heating associated with magnetic reconnection in foreshock waves: particle-in-cell simulation analysis". pic_data....zip (4 files) contain PIC simulation data in the binary format.<br> pic_data_x120-180_y-30-0_part1.zip and pic_data_x120-180_y-30-0_part2.zip are for the sub-domain of x=120~180 di, y=-30~0 di<br> pic_data_x120-180_y30-60_part1.zip and pic_data_x120-180_y30-60_part2.zip are for x=120~180 di, y=30~60 di.<br> For each file, the prefix (e.g., bx, ey, ne, etc.) indicates the quantity. The number in the suffix indicates the time step in units of omega_pe^-1, where 3733 omega_pe^-1 corresponds to 0.5 omega_ci^-1. <br> Each file contains float data arrays with a size of 6272x3136x1, corresponding to x-y dimensions. Data can be read by softwares like IDL, python, Matlab, etc, using the standard data reading method. fermi_dat.zip contains data for the Fermi decomposition calculations shown in Figure 8. Each file is for one event. The 3 columns are for time (twci), Fermi_xy, and Fermi_z. Fermi_xy and Fermi_z are for the unit area, and the total Fermi term is equal to Fermi_xy+Fermi_z. je_te_dat.zip contains data for Te and je.E decomposition, used to produce Figures 4 and 6. Each file is for one event, where the region is shown in the filename. The columns are: time (in twci), number of X-lines in the region, total je.E (integrated over the area), jepara.Epara, jeperp.Eperp, sum of the perpendicular jeperp.Eperp decompositions (ideally should be equal to jeperp.Eperp value), Fermi, Betatron, magnetization, demagnetized (jeperp.Eperp in regions with K&lt;1), average Te over the area, delta_Te/miVA^2 where delta_Te is the average Te over the area subtracting the minimum Te in the area, and VA is based on the average |B| and n in the area delta_Te/miVA^2, where delta_Te is the same as above, and VA is based on the magnetic field amplitude in the x-y plane average Te over 2di x 2di surrounding X-line delta_Te/miVA^2, where delta_Te is the average Te over 2dix2di subtracting the minimum Te in the area, and VA is based on average |B| and n in the area average Te over 2dex2de surrounding X-line delta_Te/miVA^2, where dleta_Te is the average Te over 2dex2de subtracting the minimum Te in the area, and VA is based on the magnetic field amplitude in the x-y plane delta_Te/miVA^2, where dleta_Te is the average Te over 2dex2de subtracting the minimum Te in the area, and VA is based on the average |B| and n in the area average |B| in the area average magnetic field amplitude in the x-y plane average density n minimum Te in the area je_te_norx_dat.zip contains Te and je.E data for non-reconnection current sheets. The format is the same with je_te_dat.zip thickness_data_plots.zip contains plots for individual current sheets at the time with a minimum thickness. The filename contains information about the current sheet, for example: cs_te_twci15.5_x45.292_y8.184_dte-1.07_d3.2_dve6.1_jm0.23.png means it is at the time twci=15.5, the X-line location is at x=45.292di, y=8.184 di, delta_Te/miVA^2 is -1.07%, where we take a cut along N across the X-line, delta_Te is the difference between the average Te in the current sheet and that just outside of the current sheet, and VA is based on the inflow parameters outside of the current sheets on both sides of the current sheet. The thickness of the current sheet is 3.2 de. The VeL shear flow at the edges of the current sheet is 6.1 VA, and the maximum jz is 0.23. The thickness information is used for plotting Figure 10.
