Analytical prediction of the flux function, compared to numerical equilibrium state, for the experiment with h = 0.7 and p₀ = 0.375. In a) we show the numerical magnetic field lines (solid black) over a contour map of the current density, with the analytical contours of A_z for inside the cusp (red dashed) and outside the cusp (blue dashed). In b) and c) we show the relative error of the analytical prediction from the numerical state for a horizontal cut (inside cusp) and a vertical cut (outside cusp) respectively.
