Spectrum in the region around the C IV emission line. The red line shows our total emission model comprised of a continuum fit plus a model for the C IV emission line. The latter is comprised of two Gaussians, one narrow and one broad. The orange line indicates where the half maximum of the emission line model is, while the green dashed lines show the full width of the half maximum. The continuum is subtracted for FWHM determination. We determine a FWHM of 5600 km s⁻¹ and estimate that C IV is blueshifted by about 1500 km s⁻¹.
