The first two columns specify the relevant spectrum. Columns 3-5 give respectively the absorbing column density, the plasma temperature and a normalisation factor (norm) equal to $\frac{10^{-14}}{4 \pi {d}^2} \int n_{\rm e} n_{\rm H} {\rm d}V$with d being the distance to the source (in cm), $n_{\rm e}$, $n_{\rm H}$the electron and hydrogen number densities respectively (in cm-3). The next three columns are dealing with the second component (power law); the seventh one gives the photon index whereas the eighth one gives the power-law normalisation. The last two columns give the reduced $\chi^2$ of the fit and the number of degrees of freedom. The quoted upper and lower values correspond to the 90% confidence interval (undetermined values are replaced by hyphens).
