Global Fe Kα lines for the case of an accreting magnetic WD assuming an EW of 50 eV for the component arising via reflection on the WD. We assume an Alfvén radius of 20 R_WD = 0.2 R_⊙. The blue histograms show the profiles with 1 eV energy bins, whereas the black lines show the results of a convolution with an instrumental response function of 5 eV FWHM. The magenta lines indicate the theoretical energies of the centroids of the Fe vi Kα1 and Kα2 subgroups (i.e. assuming Fe v target ions). We note the changes in energy of the line peaks, which amount to 2.6 eV between opposite quadrature phases.
