Line ratio diagrams as presented in Kewley et al. (2001) (solid lines). The solid lines divide AGNs from Starburst galaxies. Symbols indicate AGNs found in our survey as explained in the text, the filled (open) squares are our (van Dokkum et al. 2005) ratio estimations for AGN5, the black triangle (pentagon) represents Bzk25 (AGN26), the red star z2LAE3. SFGs located in the region typical of Starbursts are presented for comparison: DB12 as a magenta circle, BX16 as a cyan star, and the two LAEs from Finkelstein et al. (2011) as orange dots.
