\begin{table}%t3
\caption{Summary of the observations extracted from the XMM-Newton Science Archive for our investigation of the XMM-data reduction. This table shows observations performed with the {\em thin} filter. The fourth column shows the total column densities derived from the newest all-sky stray-radiation corrected 21-cm line surveys (Kalberla et al., submitted). The ${{t_{\rm total}}}$ columns show the total integration time of the observation for the MOS and pn instruments. The ${{t_{\rm effective}}}$  columns show the effective time after proton flare filtering (see Sect. \ref{spf}) for each observation in MOS1, MOS2 and pn as indicated. The accumulated integration time of the {\em thin} filter sample is $t_{\rm total} \simeq 1.6~ {\rm Ms}$ for MOS and $t_{\rm total} \simeq 1.4~ {\rm Ms}$ for pn. The accumulated effective time amounts to $t_{\rm eff} \simeq 1.25~ {\rm Ms}$ for MOS and $t_{\rm eff} \simeq 1.1~ {\rm Ms}$ for pn.
