Probability density distribution for our best-fit models, adopting a power law DM profile. Along the diagonal, the 1D histograms for the corresponding parameter given on the x-axis (and independent of the label in the y-axis) are shown, while below in the triangle the joint 2D probability distributions corresponding to the parameters given on x- and y-axis are shown. The different opacities in the 2D plots indicate the different sigma ranges. In general, the model with the radial arc is much better constrained than without. The parameters are the anisotropy β, inclination i, shear magnitude, and its orientation counterclockwise to the x-axis, for the DM profile the axis ratio q, Einstein angle θE, and the slope γ′. Additionally, we show the M/L, which is used to scale the two light components, and the logarithm of the strength of the point mass θE,  point. The prior range for the point mass is set to 108−1010M as the known limits of black holes, corresponding to log(θE,  point) between −4 and −1.
