Fits to the C IV emission line of the 38 SDSS quasar spectra. The data are shown in black, the best fitting model in red, and the continuum with the dashed red line. The source ID, the name of the SDSS spectrum FITS file, and a flag for the X-ray normal (N), X-ray weak (W), and X-ray-weak candidates (w) are shown at the top of each panel. Grey shaded areas highlight bad pixels and/or strong absorption features that are either masked in the fit or considered in the fit to improve the least χ².
