In Figure , we show the current density of 1 partitioned into contributions from the σ-and π-system. If the σ-and π-contribution were added together, we get exactly the current density shown in the left column of Figure . Note that, while the contribution from the σ-system seems substantial as per the size and amount of the arrows, this is due to how the arrows are scaled, filtered and plotted. The contributions from the σ-and π-systems are plotted separately, meaning that the arrows of the σ-system are scaled and filtered according to the largest arrow of the σ-system. Likewise for the π-system.
