Best-fit model SED to the redshift- and extinction-corrected observed spectrum. The contributions from the stellar and ionised gas components are shown by green and blue lines, respectively. The sum of both stellar and ionised gas emission is shown by the red line. Evidently, the spectrum in the whole wavelength range  ~λλ3200–24 000 Å is fitted quite well despite the strong absorption features in the NIR caused by telluric lines. (A colour version of this figure is available in the online journal.)
