Notes. The power law normalisation (normalised at 1 keV) is in units of photons keV−1 cm−2 s−1, while units for the column density and ionisation parameter are 1022 cm−2 and erg s−1 cm, respectively. The normalisation of emission and absorption lines are in photons cm−2 s−1. Finally, a † is used to identify the parameters kept frozen during the fit while the ⋆ specifies the component whose parameters were tied between the observations.
