Dark matter density profiles for the dark matter models studied in Sects. 5.2–5.4. The top (bottom) shows the Case 1 (Case 2) mass models. In each panel, two reference haloes are plotted. One halo (black dashed line, same for both panels) having a mass expected from an SHMR and a concentration from the c₂₀₀ − M₂₀₀ relation. The other halo (blue curves, different among the panels) instead has a halo mass similar to what we measure for Case 1 and Case 2 and a concentration from the c₂₀₀ − M₂₀₀ relation. The grey region illustrates the approximate extent of our rotation curve.
