Profiles in the magnetised Bondi flow. Magnetized Bondi flow at \(t=100\mbox{ M}\) in MKS coordinates with \(\sigma=10^{3}\) at the inner edge of the domain. The black solid curve indicates the initial exact solution. We show two realisations with resolution \(N_{r}=100\). Black crosses are with the standard treatment for the inversion. Red crosses switch to the entropy evolution at \(\beta\le10^{-2}\) (here in the middle of the domain). In particular, the error in the radial three-velocity \(v^{r}\) decreases when switching to the entropy evolution.
