Orthogonal slice through the flux rope (shown in the bottom-left panel of Fig. 4) to illustrate the twist of the field (yellow arrows) as well as ȷ/B values in the background at t = 11 240 s, before the main reconnection event (left). Full extent of the simulation box including a more comprehensive picture of the flux rope, with the orthogonal slice of ȷ/B values to indicate where the cut was taken (right). The green rectangle indicates the field of view of the left panel.
