Top panel: minimum reduced chi squared versus the inclination, i, of the model for three different values of the mass-to-flux ratio, λ, and b₀ = 0.1. Solid (dashed) lines show for positive (negative) values of i. For a better comparison, negative inclinations are shown in absolute value. Bottom panel: reduced chi squared versus the orientation on the plane of the sky for i = − 45°. The inset shows a zoom around the minimum of . The color coding follows that of the upper panel.
