Notes:
a Column densities ($N_{\rm H}$) are given in units of 1021 cm-2 for the neutral, collisionally ionised (CI) and photoionised (PI) absorbers.
b The width $\sigma_v$ of the absorption lines is expressed in km s-1.
c Temperatures, T, are in eV for the collisionally ionised gas and in keV for the blackbody.
d The normalisation (norm) of the powerlaw is given in $10^{44} {\rm ~ph~s^{-1}~keV^{-1}}$ at 1 keV. The normalisation of the blackbody is in units of $10^{15} {\rm ~cm^{2}}$.
e The normalisation of the emission lines (OVII and OVIII) are expressed in units of $10^{42} {\rm ~ph~s^{-1}}$.
f The FWHM of the emission lines is in Å.
