Moment 1 maps of the SO 4₄–3₃ transition (left) and the H₂O 183 GHz line imaged with a robust parameter of 0.5 (middle) and 2.0 (right). The orange and purple contours indicate the emission above 5σ in the SO channel at 8 and 10 km s⁻¹ tracing primarily the molecular outflow and the streamer, respectively, where 1σ corresponds to 0.3 mJy beam⁻¹. The beam of the respective moment 1 maps is indicated in the bottom-left corner of each panel, and a 20 au scale bar is shown in the right panel.
