Fig. 2


Two examples of both SN II spectra (upper panels, at epochs close to 50 days post explosion) and host H ii-region spectra (lower panels). Left: SN 2003bl, a SN with relatively high Fe ii 5018 Å pEW and O3N2 abundance, and right: SN 2007oc with relatively low Fe ii 5018 Å pEW and O3N2 abundance. The position of the Fe ii 5018 Å absorption feature in the SN spectra is indicated in blue. In the H ii-region spectra we indicate the position of the emission lines used for abundance estimations: Hβ in green, [O iii] in cyan, Hα in blue, and [N ii] in magenta.
