Goodness of fit (χ²) as a functionof the inclination i and the position angle of the ascending node Ω for the photocenter orbit of the π Men system using the spectroscopic orbit from Butler et al. (2006; left), and the revised orbit presented in Table 2 (right). Dashed lines (black and white) denote areas enclosing 68, 95, and 99.7% of the probability. The value of calculated using an unperturbed five-parameter fit is also plotted (red dashed line). The lowest χ² is indicated by the cross, and the inclination of π Men c from Huang et al. (2018) is plotted for reference (horizontal dashed line).
