Zoomed-in view of Fig. 3, showing the knots in the area of interaction between the two outflows and their proper motions. The blue-lobe pre-collision axes of outflows N and S are indicated respectively by the magenta and blue dash-dotted lines. Their intersection, the collision point O, is marked with a green asterisk. The dashed lines show the post-collision axes of outflow N (magenta) and outflow S (blue) (see Table 3).
