Integrated intensity maps (moment-0) of the SWAN dataset (combined NOEMA and IRAM 30m observations) for the J = 1–0 transitions of ¹³CO, C¹⁸O, N₂H⁺, HCO⁺, HNC, HCN, C₂H(1–0 and HNCO(J = 4–3) plus HNCO(J = 5–4) at their native angular resolution (∼2.3 − 3.1″). The maps were created with the GILDAS Island-method. We show the beam size in the bottom of all panels as well as a 1 kpc scale bar in the top left panel.
