Results for the homogenized Lindegren (2020a) data set 41,DR2 that includes more realistic uncertainties for the absolute VLBI star positions. The upper row shows the orientation and spin parameters for 38 different adjustment solutions, where for each adjustment solution the star with the largest (Qi/ni) was rejected in the following iteration. The respective (Qi/ni) and the star names are given in the lower-left plot. The lower-right plot represents the quality of the fit, equivalent to the χ2 of the adjustment, the so-called Q/n.
