Observed and synthetic spectra of J0929+0333. The abscissa corresponds to the rest frame wavelength in Å; the ordinate is the flux normalized to the continuum at 1350 Å. Left: black line: observed spectra minus the continuum; pink: model fit using specfit. The BC emission of AlIII and SiIII] are shown in purple, CIII] emission is shown in red, and the Fe III template is shown in green. Right: black line: the synthetic spectrum composed of the sum of the emission line components plus noise. The BC emission of AlIII (the sum of the doublet) and SiIII] are again shown in purple, the CIII] emission and the Fe III template are shown in red and green, respectively.
