Optical spectra of our TNG targets. These spectra are extracted from the central 1.65 arcsec of the galaxies. The fluxes are in units of 10^-15  erg s^-1 cm^-2. The red dotted vertical lines indicate the position of the main optical emission lines, while the green crossed circles on the bottom of the spectra indicate the position of the main telluric absorption lines. On the upper left side of the spectra the source redshift is indicated below the target name.
