Zoom into the CIV and MgII line fit and into the Ly_α+NV region. Left and central panel: total spectral fit (red line), and the different components, i.e., power law + Balmer pseudo-continuum (blue line), Fe II template (orange line, from Vestergaard & Wilkes 2001), and emission lines (purple). For the MgII, we represent the two lines of the doublet (solid Gaussians and dashed Gaussians, respectively). Spectral regions used for the continuum fits are shown as horizontal light blue shaded areas. In the right panel, the absorption feature in the middle of the MgII line is masked (gray dotted line). Right panel: Ly_α and NV spectral region. The blue vertical lines represent the positions of the two BELs based on the MgII line redshift. The cyan shaded region is the uncertainty on this redshift estimate. The top x-axis reports the rest-frame wavelengths while the right axis shows the monochromatic luminosity.
