Examples of spectral fitting results for the C IV, Mg II, Hβ, and Hα line complexes. In the upper panels, the black lines show the rest-frame continuum-subtracted spectra. The dashed blue and dotted green lines represent the broad and narrow emission-line models, respectively, and the solid red lines indicate the combined best-fit model of the broad and narrow lines. The lower panels show the fitting residuals.
