Notes. H i and H2 particle density for different equivalent radii with corresponding 1σ uncertainty, extracted using the information given in Fig. 14 and using Eq. (14). The given uncertainties are the statistical uncertainties, but do not take the systematical uncertainties due to the saturation of the optical depth spectra into account. The model parameters φmol and φCNM are calculated using Eqs. (17) and (15), respectively. The parameter φCNM is calculated for solar values (G0 = 1, Z = 1) and for more realistic values of W43 (G0 = 5, Z = 1.4).
