Fractional ion abundances of iron as a function of the hydrogen column density inside the warm absorber medium for the two hot modeling cases of ξtot = 2000 erg cm s-1 (top-left) and ξtot = 8000 erg cm s-1 (top-right). For ξtot = 8000, the origin of the horizontal scale is at 4.1 × 1022 for easier comparison with the case of ξtot = 4000 plot (see text). The ratio between radiative and gas pressure for the uniformly hot (bottom-left) and cold (bottom-right) solutions are shown using the same color codes as in Fig. 5. The horizontal, dashed lines mark the pressure ratios at which the two thermal instabilities occur.
