Schematic view of spatial distribution of different molecules and their relation with different velocity components in Ser-emb 8 (N) outflow. (a) In colorscale the CO moment 0 map is shown integrated over the EHV velocities, also overlaid on the following plots; (b) contours are SiO EHV emission captured at high spatial resolution, i.e., below 40 km s⁻¹ ; (c) H₂CO EHV emission (available only at low spatial resolution - synthesized beam is 1.′′65 × 1.′′13); (d) SiO fastwing emission; (e) HCN fast wing emission. The synthesized beams of continuum (black) and contour map (red) is shown in bottom-left corner.
