Notes. We show ranges of values corresponding to the uncertainty interval. NCO is the column density of 12CO, Tkin the kinetic temperature of the gas, and n the local density of H2. The parameter log10(χ2) gives the minimum value of χ2 within the minimization diagrams presented in Fig. 12 and M is the mass measured using the [H2 ]/[12CO] ratio. The parameter Ngrid is the range of column densities parsed across the grid of models, Tgrid the range of kinetic temperatures, Tb and Δv are the background temperature and width of the emission line used by RADEX for all models, respectively. The ratio MLVG ∕MLTE of the estimate of the mass with the LVG approach is indicated with respect to the results obtained with population diagrams (Sect. 4.2.2, Table 5).
