J232617 orbits and mass-distribution from the MCMC algorithm. For the left panel, we randomly picked one hundred orbits from the MCMC solutions represented by the grey lines, and plotted the astrometry with the errorbars in blue. The black line represent the Maximum A Posteriori (MAP) estimate, i.e. the most likely solution. For the right panel the blue lines depict the peak probability and corresponding dynamical mass, with the shaded light-blue area encompassing the 16 − 84 % confidence interval.
