Résumé : We noticed a typo in Eq. (6), Sect. 7.2 of the original paper: the normalizing factor 1=N was erroneously omitted, though it was included when computing the reduced χ2 listed in Table 1. The correct equation is the following: (Equation presented) where [X=Fe]obs and [X=Fe]mod are the measured and predicted abundances of a given element X, respectively, and σX,obs is the associated uncertainty on the measured abundance; the number of considered elements is N.
