Spectrum for interval p0 with the model with two absorbers displayed in Table 5 overplotted in magenta for comparison with Models 2b and 2c (which have only one absorber, overplotted in blue and in red), respectively (see Tables 3, 4 and 5 for fitted parameters). The insets show details of the Fe XXV and Fe XXVI Kα regions highlighting the different predictions of the three models for the Fe XXVI spin-orbit doublet ratio.
