Net rotation velocity curve calculated by adding the contribution of the stellar disk and the dark matter halo quadratically as (where the disk is taken to be razor-thin and has an exponentially falling surface density) so as to obtain the best-fit to the observed rotation velocity data (Uson & Matthews 2003). This gives the best-fit parameter values for the dark matter halo (ρ₀ = 0.126 M_⊙ pc⁻³, R_c = 1.4 kpc). This curve clearly shows that the dark matter halo dominates the dynamics of this galaxy at almost all radii.
