r (Rg) 1 –1.1 1.1–150 150
NH MARCS Interpolation by function from Shagatova et al. (2016)(a) 104 cm−3 (Wood et al. 2016)
T MARCS Interpolation by exponential + linear function 30 K (Wood et al. 2016)
Pe MARCS Interpolation by exponential function 10−17 dyncm−2 (dense ISM clouds)(b)

Notes. More details can be found in Sect. 3.2. (a)With the condition that for r = 3 Rg, NH equals the value of model J from Shagatova et al. (2016). (b)Derived for a typical value of the ionization fraction of 10−6 (Williams et al. 1998; Caselli 2002; Bron et al. 2021).
