Upper panel shows reconnected fluxes obtained in the FlipMHD code (black), Stagger code (dark blue), Hybrid code (red) and full kinetic iPIC3D code (green) for single layer setup with L_x/L = 240 and reconnected fluxes obtained in the FlipMHD code (light blue), MPI-AMRVAC code (magenta) and hybrid code (yellow) for double layer setup with L_x/L = 30. Lower panel shows reconnection rate (time derivative of reconnected flux) for the same data sets.
