Notes. Column (1): molecular species; Col. (2): adopted kinetic temperature; Col. (3): adopted gas density; Col. (4): our column densities; Col. (5): column densities derived from data of Menten et al. (1999) (Me) and Muller et al. (2011) (Mu) in the way described in Sect. 4.3; Cols. (6) and (7): same as Cols. (4) and (5), but relative to the adopted CO column density, NCO = 3 × 1018 cm-3 (Sect. 4.3); Cols. (8) and (9): same as Cols. (4) and (5), but relative to the adopted H2 column density, NH2 = 3 × 1022 cm-3 (see Sect. 4.3).
