Notes. The X-ray spectral results are from Corral et al. (2011), except for the new optical identifications, marked with ‡ (this work; OBSID of the XMM–Newton observations: 0094400101 and 0094400301 for XBSJ051413.5+794343 and XBSJ080411.3+650906, respectively; a paper reporting an update of the spectroscopic identifications is in preparation). Fluxes and luminosities refer to the MOS calibration. For all but one sources, the best-fitting model is an absorbed power law. † For this source, a best fit is not found (i.e. null hypothesis probability <10 per cent with all the model tested; see Corral et al. 2011); we adopt the absorbed power law as best fit, as none of the additional components significantly improves the fit. ★ mark the XQSO2s for which we obtained new XMM–Newton observations: for these sources, more complex models (applied to the new data) are tested in Appendix A and the results are reported in Table A2. Here, we quote the values derived for the most significant properties (column density, photon index, observed flux, and intrinsic luminosity; second row). m For this source, only MOS cameras have been considered, because in the pn the source falls in a CCD gap.

Column (1): source name in the XBS sample. Columns (2) and (3): J2000 coordinates of the X-ray object. Column (4): source redshift. Column (5): optical classification, from Caccianiga et al.

Column (6): total EPIC counts (0.3–10 keV). Column (7): sample to which the source belongs. Column (8): Galactic column density, from Dickey & Lockman (1990). Column (9): source photon index, and 90 per cent confidence errors; f = parameter fixed during the fit. Column (10): intrinsic column density. Column (11): observed flux (deabsorbed by our Galaxy) in the 2–10 keV energy band. Column (12): intrinsic luminosity in the 2–10 keV energy band.
