Zeroth-, first-, and second-moment maps of the different species surveyed with NOEMA. Left: tntegrated intensity maps (zeroth-moment maps). Center: intensity-weighted velocity maps (first-moment maps). Right: velocity dispersion maps (second-moment maps). From top to bottom: species are ¹²CO, ¹³CO, C¹⁸O, H₂CO, and SO. The maps were obtained after integrating channels in the range 3–9 km s⁻¹. For the first- and second-moment maps, only channels with a S∕N > 5 were used.The white ellipses in the bottom left corner of each map depict the synthesized beam at each wavelength.
