Posterior parameter distribution of the initial conditions of Jhelum’s best-fit orbit and of the parameters of the Galactic halo potential, for σnuis = 6.7 km s−1. We note that here, the bulge and disk were kept fixed and set to be those of the default MW potential. The posterior parameter distribution of the initial conditions resembles the one of the default MW potential shown in Fig. 5. There is a strong degeneracy between Mh and rs, as expected, and is a result of the circular velocity constraint. The correlation between qx and qz is set by the requirement that the halo density be positive.
