Pseudo-streamer topology at the end of the relaxation phase. The magnetic field at the solar surface is colored in gray scale. The white lines draw the polarity inversion lines. The green loops materialize the PS closed dome separatrix, the dark blue lines show the open section of the vertical fan associated to NP₂. The sections of the red and yellow lines above the PS dome (green lines) show the closed section of the vertical fan while the section of the red and yellow lines lying along the green field lines show the closed fan associated with the secondary null points (NP₁ and NP₃).
