Comparison between the stellar surface density profile of Nube and the best-fitting potentials with f ≥ 0. The plot shows the mass surface density that gives rise to the best-fitting Schuster-Plummer potential (blue line), NFW potential (green line), and ρ₂₃₀ potential (magenta line). The spatial scaling of the potentials is set by the fit whereas the vertical scaling is arbitrary, and it was arbitrarily chosen to be 30 times the stellar mass of Nube.
