Comparison with HCN observations from Querejeta et al. (2019) (Q19). Left panel: SWAN HCN moment-0 map with contours (∼5, 50, 200σ with σ the average noise) of Q19 HCN maps. Both maps are at 3″ resolution, spatially and spectrally regridded to the same grid, and the maps were created via the same GILDAS island method (using just the HCN line). Circles depict radii of 35″ centered according to Q19. Right panels: Average spectra of SWAN 3″ data at 10 km s⁻¹ resolution as well as the matched Q19 data. Spectra are the average flux inside of the circular area shown in the left panel.
