Zoomed-in view of the profiles of intersecting magnetic field lines at θ = 13° (panels a and c) and at θ = 3.7° (b and d). Panels a and b: configuration before the magnetic reconnection, where the connectivity (dashed red arcs) connect (, P, ) and (, P, ). Panels c and d: configuration after the magnetic reconnection, where the connectivity changed (dashed red arcs) and the connected points are (, P, ) and (, P, ). In panels c and d the length of the blue arrows is proportional to the inverse of the curvature radius of the dashed red arcs (defined by the circles passing through those points), and their directions point towards their centres of curvature.
