* The abundance parameter was left as a free parameter.
** The spectra were extracted using a 40 arcsec radius circle for both Swift-XRT and XMM-Newton data. Extended source ARFs were specially created to fit the XRT spectra.
$^\dagger$ The values of the observed flux are given in the 2-10 keV energy range.
c The model is CONST*TBABS(BBODYRAD+BBODYRAD) (see Beuermann et al. 2006). All the parameters are fixed ( $N_{\rm H}=1.1$ $\times $ $10^{20}~{\rm cm}^{-2}$, kT1 = 62.8 eV and kT2 = 32.3 eV) except the constant factor. The lowest temperature black-body component has a minor impact in the XRT energy range. It was introduced by Beuermann et al. (2006) to fit the EUVE data as well as the Chandra data.
$^\ddagger$ Values of the constant factor for the model described in Beuermann et al. (2006).
