Confidence intervals for the axisymmetric Vogelsberger model in (log₁₀(M_1 kpc, R_s) (after fixing c/a = 0.8) for a kinematic dataset with 10⁵ stars and 9 × 9 kinematic bins. The Δχ² = [2.3, 6.18, 11.8]-contours are in white, grey, and black, respectively. The best-fit model is indicated by the white cross, while the expectations are given by the green contour (identical to that shown in Fig. 6). The mass parameter is well constrained and models with R_s ≤ 2.0 kpc are strongly disfavoured, consistent with our expectations. The small panels on the right show the Δχ² landscapes when only considering (top), (top-middle), (bottom-middle), or (bottom).
