Notes. The columns report the identified line, its rest and measured wavelength, the FWHM and flux obtained as detailed in the text. Errors on the flux and FWHM measurements are of the order of 10%. The spectrum was redshift and reddening corrected with the values reported in Table 1.
Affected by absorption features, as described in Section 5.
