Close-up views of the spectral fit of the C IV and Mg II BELs. The orange curves depict the models we fit, which consist of Gaussian components for the emission lines and a continuum model (see text for details). The transparent vertical blue line indicates the position of the lines based on the redshift reported in Table 2 (i.e., the Mg II-based redshifts). The same redshifts were used to draw the rest-frame wavelength x-axes. To fit the C IV line in the spectra of PSO J067−14 and PSO J289+50, the absorption features were masked.
