Contours of a) the pressure difference (p − p₀) in the z = 0.5 plane of the final equilibrium and b) the 3D skeleton of this field with yellow/blue isosurfaces of pressure difference (p − p₀) drawn at 95% of the maximum positive/negative value. c) The plasma beta in the final equilibrium state in the plane z = 0.5. The pale-blue/pink lines indicate where the separatrix surfaces from the lower/upper nulls intersect the plane.
