Results for scenario “55,EDR3,GA”, when using the VLBI data and Gaia EDR3 as in Fig. 3 in Lunz et al. (2023) but correcting for the effect of Galactocentric acceleration. The orientation and spin parameters for 51 different adjustment solutions are shown in the upper row. For each adjustment solution the star with the largest (Q_i/n_i) (which indicates the quality of the fit of the star data to a five parameter astrometric model, see Lindegren 2020a) was rejected in the following iteration. The respective (Q_i/n_i) along with the star name are shown in the lower left plot, whereas the lower right plot shows the quality of the overall fit Q/n, equivalent to χ² of the adjustment.
