Illustration of the inferred mass profile of the joint TDCOSMO+SLACS_{SDSS + IFU} analysis. A pure power-law with γ_pl = 2.10 ± 0.05 is shown in orange. In blue is the result of this work of λ_int = 0.91 ± 0.045 when interpreted as a cored mass component with R_c uniform in [3″, 10″]. Three dimensional density are illustrated on the left and the lensing convergence on the right. The dashed vertical line on the right panels indicates the Einstein radius. Relative difference in respect to the power-law model are presented in the bottom panels (https://github.com/TDCOSMO/hierarchy_analysis_2020_public/blob/6c293af582c398a5c9de60a51cb0c44432a3c598/MST_impact/MST_pl_cored.ipynb).
