Notes. Quantities in italics are assigned.
These metallicities are weighted averages of all the elemental abundances listed in Tables 2–4 of Acke & Waelkens (2004); see Appendix A of Montesinos et al. (2009) for details.
Metallicities assumed to be in the same proportion as the species [Fe i]/([Si ii])/[Fe ii], respectively (see Table 3 of Acke & Waelkens 2004).
