Top: contribution to the rotation curve of different baryonic models and model components. Red points indicate the rotation curve of the Milky Way from Eilers et al. (2019). The error bars are estimated by bootstrapping and include the systematic uncertainties from the neglected term (see text). Bottom: fit of the rotation curve by the best-fit model (solid blue curve, total mass of 2.8 × 10¹¹ M_⊙), and with the most massive MW model for which the χ² probability reaches P = 0.05 (dash-dotted orange line, total mass of 18 × 10¹¹ M_⊙), both associated with the baryonic distribution from model I of Pouliasis et al. (2017).
