Position-velocity cut of SiO(5–4) (grey scale and black contours) and SO(65–54) (magenta contours) along the whole E-W jet (PA = 105°, see the grey line in Fig. 1). First contours and steps correspond to 5σ (2.5 K for SiO and 4.0 K for SO) and 3σ, respectively. Dashed lines mark the positions of MM2 and the protostellar envelope VLSR (+6.5 km s-1). We note that the SiO and SO emission at negative angular offsets traces the N-S outflow driven by MM1 (see Fig. 1).
