Fig. 11.
Left: Fe K line strength indicator, R(Fe), against the Fe K line equivalent width (EW) obtained from spectral fitting. The filled squares (red) show data for Fe lines with the ≥90% detection while the circles (light blue) show data for weak/no detection for the whole sample. The dashed line indicates the fitted linear correlation (see text). The dotted line indicates the expected relation when the continuum level estimate of the i = 13 bin is accurate. Right: same plot for the crowded region of EW < 0.8 keV.
