Examples of halo profiles and best fit in four bins of increasing mass at z = 0 in the DMO runs. We show a different dark matter model in each row. In each panel the grey lines show individual density profiles of haloes in the considered mass bin, while the black line indicates the radial range used to perform the fit (3ϵ_DM ≤ r ≤ r_200c). The Einasto and Y24 best fits to the mean dark matter profile are shown in orange and blue. In the alternative dark matter panels, we also plot the CDM mean as the dotted black line for comparison. The vertical dashed lines of corresponding colour mark the two scale radii r_E and r_Y, while the vertical dotted blue line stands for the Y24 core radius r_c. As we only considered systems with more than 1000 particles, we do not show the profiles of WDM1 haloes in the first mass bin.
