The complete figure set (50 images) is available in the online journal.
Two examples (left: RM161; right: RM139) of SDSS-RM SE (top panels) and coadded spectra (bottom panels) are shown in black. The best GH fits to the C IV emission lines are shown in red, the best multi-Gaussian fits are shown in cyan, and the best linear continuum fit is in green. The wavelength scale has been shifted to the rest frame based on the SDSS pipeline redshift, and the vertical black dashed lines show the expected location of the labeled emission lines. The red vertical solid lines show the boundaries of the two wavelength regions used to fit the continuum beneath the C IV emission, and the red vertical dashed lines bound the wavelengths over which the C IV line properties are measured. Shaded regions were masked during the fitting. The figure set contains similar figures of the coadded spectra and fits for 50 randomly selected objects from our sample.
