Fig. 7.
Top left panel: ξCIVFWHM(C IVλ1549) i.e., FWHM(C IVλ1549) after correction for blueshift and luminosity dependence following Eq. (6) vs. FWHM(Hβ) cm for the FOS+HE sample. The black dot-dashed line is the equality line, and the meaning of the color-coding is the same as in Fig. 3. Top right: as in top panel but with ξCIV computed from Eq. (7).
