Fig. E.1

Conversion factors between line intensity and derived column density assuming optically thin emission. Top panel: CO (2−1) (black), SO (56−45) (red), and SiO (5−4) (blue) conversion factor assuming LTE. Bottom panel: SiO (5−4) conversion factor for various kinetic temperatures as a function of the gas density computed by RADEX (non-LTE).
