Notes. Columns are (from left to right) the target name, epoch ID as in Table 3, measured positions in the VLBA images and their statistical errors derived from JMFIT, and the estimated offset between the radio source detected with the VLA and the radio source detected with the VLBA (Δαradio ${\rm{\Delta }}\alpha _{{\rm{radio}}}^ * $, ∆δradio, and ∆θradio). The offsets ∆α*, ∆δ, and ∆θ are the angular separations between the radio source (VLBA) and the Gaia DR3 predicted position at the observed epoch in right ascension, declination, and total, respectively. The column σsys is the position systematic error expected from the phase difference of the target and its phase calibrator, given their angular separation. Finally, column ∆λ, which is derived from ∆θ, is the linear separation in astronomical units at the corresponding distance (see Table 1).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
