Example WEST and ITER: Contour Lines. Contour lines of the magnetic flux ψ for WEST (left) and ITER (right). The location \((r_{\mathrm{{max}}}(\psi),z_{\mathrm{{max}}}(\psi))\) of the maximum of ψ is indicated with a green circle. The location \((r_{\mathrm{X}},z_{\mathrm{X}})\) of the discrete saddle points of ψ is indicated by black circles. The magenta line indicates the contour line that contains the plasma boundary
