Fig. 2
[OIII]/Hβ vs. [NII]/Hα line ratio diagram for our sample galaxies. Different spectral types following the scheme of Kewley et al. (2006) are represented by different colored symbols (Seyfert: red, LINER: pink, composite: green, SF: blue, ambiguous: black). The solid and dashed lines indicate the extreme starburst (Kewley et al. 2001) and pure SF limits (Kauffmann et al. 2003a), respectively.
