Erratum for: A&A 559, A47 (2013), DOI: 10.1051/0004-6361/201321096

Equation (11) of Belloche et al. (2013) is incorrect. The correct equation is provided here. The last paragraph of Sect. 3.1 should be replaced with the following paragraph:

The spectrum containing the contributions of both the “emission” and “absorption” groups is computed with the following recursive equation:$\begin{array}{ccc}{\mathit{T}}_{\mathit{i}}\mathrm{\left(}\mathit{f}\mathrm{\right)}\mathrm{=}{\mathit{T}}_{\mathit{i}\mathrm{-}\mathrm{1}}\mathrm{\left(}\mathit{f}\mathrm{\right)}{\mathrm{e}}^{\mathrm{-}{\mathit{\tau }}_{\mathit{f}}^{\mathit{m,c}}}\mathrm{+}{\mathit{\eta }}_{\mathit{f}}^{\mathit{m,c}}\mathrm{(}{\mathit{J}}_{\mathit{f}}\mathrm{\left(}{\mathit{T}}_{\mathrm{rot}}^{\mathit{m,c}}\mathrm{\right)}\mathrm{-}{\mathit{J}}_{\mathit{f}}\mathrm{(}{\mathit{T}}_{\mathrm{bg}}{\mathrm{)}}^{\mathrm{)}}\left(\mathrm{1}\mathrm{-}{\mathrm{e}}^{\mathrm{-}{\mathit{\tau }}_{\mathit{f}}^{\mathit{m,c}}}\right)\mathit{,}& & \end{array}$(11)where m is the index on the species that have at least one “absorption” component, c is the index on the “absorption” components of each species m, and i is the recursivity index varying from 1 to N_a, with N_a the total number of “absorption” components (see Fig. 1). T₀ is initialized to the spectrum of the “emission” group T_emg. T_Na is the final spectrum containing the contributions of all “emission” and “absorption” components.

All calculations in the original publication were performed with the correct equation. All results and conclusions of this work are therefore unaffected.
