Caption: Figure 7.
Left panel: the best-fitting FWHM line width of the O VII(i) line vs. its observed luminosity. Right panel: FWHM line width of the N VI(i) line vs. its observed luminosity. The left y-axes on each panel show the line widths in Å, while the right y-axes show the velocity widths in kilometers per second.
