Position-velocity diagrams of the H¹³CO⁺ (top panels), CCH (middle), and c-C₃H₂ (bottom) emission from the areas highlighted in Figure 1. The left panels show the redshifted emission of the putative second outflow, and the right panels show the blueshifted emission counterparts. The dashed lines represent the systemic velocity of the source, v_sys ~ 3.6 km s⁻¹. The arrows in the redshifted panels correspond to the transition between the rotating envelope and the outflowing gas, as also specified in Fig. 1. We employed a logarithmic color scale to emphasize the shape of the velocity curve of the outflowing gas.
