Note: Only the set of 10 best \xmm\ observations (see text) and the \chan\ one are shown. The best fit parameters (derived using the maximum likelihood $C$ statistic) listed are for an absorbed blackbody model for which all parameters were allowed to vary freely (middle column). The right column shows the blackbody temperatures obtained when the column density is held constant at the mean value, $\nh=3.5\times10^{21}$~cm$^{-2}$. Errors are 1$\sigma$. The observed flux $f_{\rm X,14}$ refers to ranges 0.15$-$3~keV and 0.5$-$3~keV for \xmm\ and \chan\ data, respectively, in units of $10^{-14}$~erg~s$^{-1}$~cm$^{-2}$. The ``goodness-of-fit'' is derived from 1000~Monte Carlo simulated spectra.
