Integrated emission and velocity maps of SO₂, OCS, H₂CO, and HCN created using the long+short baseline data. These molecular lines trace a larger extended emission in IRAS4A2. We identified these features visually from the spectra as the most intense and spatially extended emission lines. The white and black contours represent the 6 to 60σ levels of the continuum emission from the ALMA Band 6 and Band 4 data, highlighting the underlying dust distribution. The synthesized beam is shown in the lower-left corner of all panels, and the dashed green lines indicate the cuts used to extract the P-V diagrams perpendicular to the outflow axis.
