PION absorption models for each warm absorber component (1–3 from top to bottom). These plots help demonstrate what the model looks like with the parameter values from Table 2: large ξ means absorption at higher energies; large N_H means stronger absorption lines. The Galaxy absorption transmission is overlayed in orange for a comparison. The Galaxy absorption affects the continuum emission, especially at longer wavelengths, causing the transmission to decrease. As a consequence of the RGS resolution, weak narrow lines are not evident in Fig. 1 due to the low equivalent width, but can be seen in these models.
