Example of posterior distribution on the enclosed mass within S2’s orbit, for an MCMC analysis with 200 000 realizations, showing how the 1σ and 3σ upper limits are derived. This example corresponds to the case of a multi-star fit with the stars S2, S29, S38, S55 for a power-law density profile with slope s = −2.2.
