Notes. (a) We give the separate fits for the two observations only for Model A in order to show that they are consistent within the errors and thus can be fitted together. C-Stat/d.o.f. (*) Refers to the statistics obtained by including the wavelength ranges 17.2-17.7 Å and 22.7-23.2 Å, which in fits are ignored except in the case of the complete model. (b) All columns for the dabs and amol components are reported in units of $10^{21}~{\rm m}^{-2}$. (c) Each amol component is displayed together with its molecular index as reported in Table A.1.
