Table 5.

Best-fit parameter values for our model based on the power law DM distribution with dynamics-only.

Component Parameter Best-fit value Marginalized
Kinematics β 0.10
i 0.1

Dark matter q 0.82
(power law) θE [″] 2.3
rc [″] ≡10−4
γ 1.20

Baryonic matter M/L [M/L] 1.8

Notes. The parameters are the anisotropy β, the inclination i, the axis ratio q, the strength θE, the core radius rc, and the slope γ′. In the last row we give the M/L for the baryonic component. Since we have only seven data points with huge uncertainties and vary six parameters in this model, we get also a large range of parameter values within 1σ. The corresponding χ2 is 0.25. We do not obtain any constraints on the anisotropy or inclination, given the assumption of a prior range of β ∈ [−0.3, +0.3] and i ∈ [0, +0.3].
