Detection of current sheets using the modified algorithm based on current density J_z at time 680.12 s. The left plot shows the current density magnitude, the middle plot shows the correspondence of local maxima events using a threshold higher than the mean |J_z| with the current density (|J_z|), and the right plot shows the identification of clusters derived from density clustering methodology using local maxima events at time 680.12 s. 123 separate clusters could be identified.
