NOEMA+30 m DCO⁺(3–2) data towards ISOSS22478. The three panels show in color scale the integrated intensity, the 1st and 2nd moment maps (intensity-weighted peak velocities and velocity dispersions), respectively. These maps were produced by clipping all data below an approximate 3σ threshold of 18 mJy beam⁻¹. The contours show the 1.3 mm continuum emission in 3σ steps (1σ ~ 0.057 mJy beam⁻¹) from 3 to 15σ. The beam is shown in the bottom-left of all panels, and a linear scale bar is shown in the middle panel. The red arrows in the middle panel show the three position velocity slices presented in Fig. 8. To reduce noise signatures at the edges of the mosaic, for the 1st and 2nd moment maps, we blanked the mosaic edges. The cores are labeled in the left panel.
