Plot of EW of the Fe K line at 6.4 keV (open circles) and 6.9 keV (filled squares) measured from a) the three 2–10 keV luminosity bins or b) the three redshift bins (see Table 3). The EW is plotted against the median value of luminosity/z in each bin. Note that the high-z point for the 6.9 keV line is a sum of Fe xxv (6.70 keV) and Fe xxvi (6.97 keV).
