Notes. (a)From Table 1 in Motte et al. (2022).(b) Spatially-averaged density-weighted dust temperature, measured in the corrected PPMAP temperature map (cf. Sect. 3.4). (c)Peak H2 column density, measured in the PPMAP column density map. (d)Mass of gas, derived from the PPMAP column density map; bolometric luminosity, derived from the PPMAP MBB in addition to observations by Spitzer and SOFIA (that is, between 3.6 µm and 1.3 mm); and luminosity-to-mass ratio, measured in the ALMA footprint (cf. Sect. 3.3). (e)Mass, bolometric luminosity and luminosity-to-mass ratio measured in the ATLASGAL source footprint (Contreras et al. 2013; Urquhart et al. 2014, cf. Sect. 3.3).
