Notes. The model in Xspec is tbabs*cabs*edge*warmabs *(gaussian+gaussian+diskbb). Here, is the column density of the warm absorbing material, log (ξ) its ionization status, σv its turbulent velocity broadening, v the bulk velocity shift, and EW the equivalent width of the Gaussian lines. The abundance of each element is indicated as a fraction of the corresponding solar value.
