Δχ²-distribution of the characteristic parameters q and v₀ of the Evans models obtained after applying the Schwarzschild method. In this case our mock kinematic data consist of 10⁵ stars inside the FOV (3 × 3 kpc). We use 9 × 9 kinematic bins and assume the functional form of the potential of the system and inclination are known. The black circles show the locations where the Schwarzschild models were evaluated. The green circle indicates the input parameters of the mock system. The best-fit model is indicated by the white cross and recovers the mock galaxy mass parameter. In white, grey, and black we show the Δχ² = [2.3, 6.18, 11.8]-contours, respectively. The coloured landscape on the left shows interpolated Δχ²-values, and goes up to a maximum of Δχ² = 10. On the right we show the Δχ²-landscapes when decomposing the landscape into (top), (middle), or (bottom). These right panels sum up to the large panel. We stress that only is being minimised in the fit.
