Notes. The data is reproduced from Sipilä et al. (2015a). The parameters presented in the left column represent the gas and dust temperature (T), cosmic ray ionization rate (ζ), visual extinction (AV), grain radius (ag), grain material density (ρg), density of binding sites on the grain surface (ns), diffusion energy to binding energy ratio (Ed/Eb), and dust-to-gas mass ratio (Rd).
