Distribution of VLBI-to-Gaia positional offset directions relative to the parsec-scale jet direction, for sources with statistically significant offsets (>3σ). The peak near 0° reflects optical jet emission shifting the Gaia centroid downstream along the jet (see A. V. Plavin et al. 2019 for a detailed study). The shaded region highlights the jet-aligned subsample (<45°) analyzed in this work. An interactive version of this figure is available at A. V. Plavin (2025).
