Rotation curves of a variety of MW mass models. We have plotted here the models by Bovy (2015), Price-Whelan (2017), McMillan (2017), and Cautun et al. (2020), and two models by Vasiliev (2024) using his ℒ3, ℳ11 and ℒ2, ℳ11 halo models at the present day. The grey line shows the rotation curve of the fiducial model (described in Sect. 2.1 and Appendix A). The black line shows the best-fit potential of this work (described in Sect. 4.2), while the grey shaded area correspond to the 16^th to 84^th percentile range for 200 potentials from the MCMC chains. The rotation curve data used in the fit includes Eilers et al. (2019)’s rotation curve data, shown in magenta, and Zhou et al. (2023)’s in yellow. The light grey shaded area marks the region R > 15 kpc and data in this distance range was not included in the MCMC fit. However, the fit is similar even if data up to R ~ 20 kpc is used.
