Density profile of the DM halo of NGC 3198 and the effective density of the other components. We assume M_D = 4.4 × 10¹⁰M_⊙. The stellar disk (blue line), the HI disk (magenta line), the dark halo (red line) and the sum of all components (green line). The different colour regions correspond to the regions a) where we do not have any kinematical information due to the lack of data (dark purple); b) where the stellar disk dominates the DM density profile (light purple) and c) where DM dominates (white).
