Notes. Columns are (left to right): Source name, RA and Dec columns give the source coordinates at epoch J2016.0 from the VLBA astrometric solutions (after applying the calibrator-position corrections described in Sect. 3.4). Δ_VGα and Δ_VGδ are the positional differences between VLBA and Gaia at J2016.0, expressed in mas and defined as VLBA − Gaia; $Δ_{VG, total} = \sqrt{Δ_{VG α}^{2} + Δ_{VG δ}^{2}}$ $Mathematical equation: $ \Delta_{\mathrm{VG,total}}=\sqrt{\Delta_{\mathrm{VG\alpha}}^{2}+\Delta_{\mathrm{VG\delta}}^{2}} $$ . Gaia positions in the epoch J2016.0 are taken directly from the Gaia DR3 catalog. RUWE is the Gaia renormalized unit weight error.
