Diagnostic diagram plotting log [O III] λ5007/Hβ vs log [S II] λλ6716, 6731/Hα for (filled circles) early‐type (S0–Sbc) H II nuclei and (open circles) late‐type (Sc–I0) H II nuclei. The curve denotes the theoretical models of disk H II regions by McCall et al. (1985) described in the caption of Fig. 7.
