Notes. We list line fluxes and vibrational band ratios. Varied parameters are: the dust/gas mass ratio, the PAH abundance, the grid size and switching CO self shielding on/off. The outcome of the various models (without slit filtering applied) are presented here by comparison of the Tvib and the line flux for two representative lines: v(2–1)R06, v(1–0)P22. All model here are unfiltered. The line sample used for the computation of Tvib is that collected on the 29th and the observational result is shown at the top.
