|Component||Density log(nH)||log(G)||log(NCO)||log(NH2)||Ωa||C em b||CNCO c||MassNH2d|
|Mtot: 2 × 109 M⊙|
|PDR I||3.5||2.5||17.1||21.5||1.2||0.11||0.61||2 × 109|
|PDR II||5.0||5.0||18.2||21.9||0.06||0.32||0.39||3 × 108|
|PDR III||6.0||6.0||16.7||21.2||0.006||0.57||< 0.01||6 × 106|
Cem is the fractional contribution of each ISM phase to the emission, as in Eq. (5).
MassNH2 is the mass of each ISM phase as estimated by the column density using Eq. (4).
