NOEMA+30 m SiO(5–4) data towards ISOSS23053. The three panels show in color scale the integrated intensity, 1st and 2nd moment maps (intensity-weighted peak velocities and velocity dispersions), respectively. These maps were produced by clipping all data below an approximate 4σ threshold of 20 mJy beam⁻¹. The contours show the 1.3 mm continuum emission in 3σ steps (1σ ~ 0.16 mJy beam⁻¹). The beam is shown in the bottom-right of all panels, and a linear scale bar is shown in the middle panel. The cores are labeled in the left panel. The arrow in the middle panel marks the position-velocity cut presented in Fig. 14.
