Notes. Y: young; I: intermediate; E: evolved. Size: length and width of filamentary clouds. Mcloud: Subregion cloud mass. LFIR: far-infrared luminosity. ⟨NH2⟩: mean column density of the region. ⟨nH2⟩: mean volume density assuming depth equal to width. ⟨Tdust⟩: mean dust temperature throughout the subregion. LFIR/Mcloud: FIR luminosity-to-mass ratio calculated at cloud scale. Lbol/Mclump: bolometric luminosity-to-mass ratio calculated at clump scale of 0.2–0.4 pc.
