Marginalised posterior distributions of a subset of the fitted orbital parameters. The black posteriors were sampled considering the previously available data only, while the green posteriors result from the inclusion of the new GRAVITY epoch from 31 May 2023. The median values and intervals between the 16th and 84th percentiles of the distribution are indicated by the horizontal bars. The inferred values resulting from the two runs, which were rounded to the respective significant figure, are displayed at the top of each panel. While technically not one of the parameters explored by the walkers during the sampling procedure, we also plot the period, P, as computed from the other posteriors via Kepler’s third law. The full posterior samplings can be found in Appendix A.
