Notes. Emission-line flux in the blue ([O III], Hβ) and red part ([N II], Hα) of the spectra are normalised by the [O III] and Hα flux of the brighter nuclei, respectively. The implied line ratios are not corrected for Galactic extinction as we use them only for the BPT diagnostics which are insensitive to extinction.
