Individual RC mass modeling. Row 1: posterior distributions (MCMC output) of the following estimated parameters: r₀ and ρ₀ for Burkert (red) and r_s and ρ_s for the NFW (blue) halo. The vertical and horizontal gray dashed lines show the initial guess for parameters r_0/s and ρ_0/s. The full posterior distribution of parameter space θ of these example cases are shown in Fig. D.1. Rows 2 and 3: best fit to the RCs and their velocity decomposition for Burkert and NFW halos, respectively. In the RC panels, the blue square with error bars represents the observed data, the blue solid line shows the best fit to the data, and the blue shaded area represents the 3σ error in the fit. The decomposed velocity of stars, molecular gas, atomic gas, bulge, and dark matter is represented by yellow, violet, light blue, brown, and black dotted-dashed lines, respectively. The vertical orange line shows the effective radius and the gray shaded area represents the unresolved region of the RC. The best-fit value of parameter space θ is given in the legend of the figures. All the parameters are printed in log, having physical units as follows: M_D [M_⊙], R_D [kpc], M_bulge [M_⊙], r_0/s [kpc], and ρ_0/s [gm cm⁻³].
