Set of two figures for those sources with a relativistic 6.4 keV (6.7 keV) Fe K_α line EW detection  ≥ 5σ confidence level: data to the best-fit continuum ratio (left set column), and data to the best-fit model ratio (right set column). The vertical dashed line is placed for reference at 6.4 keV (6.7 keV) in the rest frame of the source. On top of each figure the model used for the ratio, the corresponding source name, and the observation ID are given. For those sources with summed observations a dummy observation ID is given.
