Continuum-subtracted line centroid and moment 1 maps of our sample ordered by bolometric temperature, annotated as described in Figure 1. First and third rows: moment 1 map of CO 3–2 or 2–1 emission integrated from ±30 km s⁻¹ of the source velocity. Second and fourth rows: velocity centroid of H₂ S(1) line from Gaussian fit per pixel. All maps are integrated from −30 to +30 km s⁻¹ . For the ALMA CO maps, the low-velocity cloud at emission at v_LSR ± 2 km s⁻¹ is excluded. All maps are masked by using the corresponding moment 0 to apply a black mask with increasing transparency in brighter areas.
