Table 6: Parameters of an xabs model fit to the RGS spectrum of NGC 7469, using three phases of gas at different levels of ionisation. For each phase, the following parameters are listed: log ionisation parameter $\xi $ (erg cm s-1), equivalent hydrogen column density $N_{\rm H}$ (cm-2), and average velocity shift  $v_{\rm shift}$ in km s-1.
Phase Parameter Value
Component 1 Log $\xi $ $\rm0.8^{+0.4}_{-0.3}$
  $N_{\rm H}$ $\rm 3^{+2}_{-1}\times 10^{19}$
  $v_{\rm shift}$ $-2300 \pm 200$
Component 2 Log $\xi $ $2.73 \pm 0.03$
  $N_{\rm H}$ $(2.0 \pm 0.2) \times 10^{21}$
  $v_{\rm shift}$ $-720 \pm 50$
Component 3 Log $\xi $ $\rm 3.56^{+0.08}_{-0.07}$
  $N_{\rm H}$ $\rm 2.9^{+0.9}_{-0.7}\times 10^{21}$
  $v_{\rm shift}$ $\rm -580^{+80}_{-50}$

a Fixed.
