Comparison of the positions of the continuum emission at K-band of VLA 1 (left panel), VLA 2 (central panel), and VLA 3 (right panel) as observed in epoch 1996.96 (solid black; Torrelles et al. 1997) and epoch 2014.20 (dashed red; Carrasco-González et al. 2015; Rodríguez-Kamenetzky et al. 2020). The squares represent the uncertainties of the peaks positions (see Table B.1) and the circles are the restoring circular beam of 0.​​″12 used to properly compare the two epochs. Each panel is centered at the corresponding position of the YSO in epoch 1996.96 (see Table B.1). The positions of epoch 2014.20 are corrected for the proper motion of the region W75N(B) as measured by Rygl et al. (2012), ⟨μ_α⟩ = (−1.97 ± 0.10) mas yr⁻¹ and ⟨μ_δ⟩ = (−4.16 ± 0.15) mas yr⁻¹.
