Temperature and H₂ column density of the gas components in IRAS 23385 derived using CH₃CN and H₂ as a diagnostic tool (Sects. 3.3 and 3.4). In the top and bottom panels, the rotation temperature and H₂ column density map, respectively, of the cold (left), warm (center), and hot (right) components are shown in color. The angular resolution of the line data is indicated by a purple ellipse in the bottom right corner. The JWST/MIRI 5.2 μm continuum is presented by blue contours with contour levels at 5, 10, 15, 20, and 25 × σ_cont,5μm and the angular resolution is highlighted by a black ellipse in the bottom left corner. The NOEMA 3 mm continuum (top and bottom left panels) is highlighted by gray contours with levels at 5, 10, 20, 40, and 80 × σ_cont,3mm and the synthesized beam is highlighted by a gray ellipse in the bottom left corner. All continuum sources are labeled in green in the bottom left panel and the mm continuum sources are marked by green squares. Several shock positions are indicated by green crosses (Sect. 3.2).
