Corner plot of marginalized posterior distributions after the MCMC sampling for the removal of the binary at 37 GHz (left) and at 30 GHz (right). (∆α_j, ∆δ_j) are the offsets in right ascension and declination of the star j in the sky plane with respect to the phase centre, and F j the flux of the star j. The units are written in brackets next to each parameters. For each parameter, best-fit values are indicated and computed as the median values of the posterior distributions. The errors are computed as the 16th and 84th percentiles of the posterior distribution.
