Residuals of the DR2 observations for (367) Amicitia corresponding to the maximum-likelihood MCMC solution, computed using the DR2 astrometry alone, in terms of AL and AC coordinates (left), and in terms of RA (α) and Dec (δ) (right). Theunfilled circles represent data rejected as outliers. The scales of the plots have intentionally been chosen to match Fig. 23 of Gaia Collaboration (2018b) and thus allow for direct visual comparison.
