Comparison of the radii, column densities, and line emission temperatures of H₂O extracted from ProDiMo with the retrieved parameter conditions. In the main panel, the horizontal axis shows the radius of the emission and the vertical axis the column density. Every H₂O line with peak fluxes 3σ above the observational noise is selected to show the emitting conditions in ProDiMo. The grey lines show ${\Sigma }_{\text{col }}^{\text{line }}(r)$ within the emitting region for the respective water lines. Every circle denote R_0.15 and R_0.85 for all emission lines with the colour indicating the temperature $T_{\text{emis}}^{\text{line }}(r)$. The column density power law retrieved by DuCKLinG is shown as a red outlined bar. It ranges from R_0.15 to R_0.85 with the surface colour illustrating the temperature at every radius. In the upper panel, the radial cumulative flux of H₂O in ProDiMo (blue) with the from DuCKLinG retrieved R_0.15 and R_0.85 values with their uncertainties overplotted in red.
