FWHM of Mgiiλ2800 vs. FWHM Hβ on log scale. Left: full profiles, right: only BC (of single component for Mgiiλ2800). Gray dots are the data points of Wang et al. (2009), with the line representing their best fit. The large black spots are the median values for the full profiles of our median spectra. The dot-dashed lines traces the equality relation, and the thin red line a fixed ratio 0.77.
