The nature of the activity in these galaxies was determined using a diagnostic diagram comparing the equivalent width of [NII]$\\lambda$6584 with the ratio [NII]$\\lambda$6584/H$\\alpha$. The majority of these galaxies are AGN. The H$\\alpha$ emission lines have a mean FWHM of 400 km s$^{-1}$ and mean luminosity of 5.6$\\times$10$^{39}$ erg s$^{-1}$, which justify their classification as LLAGN.
