Notes. All count rates, fluxes and luminosities quoted in this table refer to the 0.3–10 keV energy band. The errors on the spectral parameters refer to 90% confidence levels. For each source we list the total number of detected counts (Ncounts), the expected (exp.) and observed (obs.) XRT count rates (see text), as well as the the ratio of these two (expected/observed). We give both the Galactic (; from Kalberla et al. 2005) and observed (NH) hydrogen column density for each source. The X-ray luminosity is expressed in units of 1034 erg s-1 and calculated from the unabsorbed flux (FX,unabs) by assuming a distance of D = 8 kpc for all sources, except AX J1754.2–2754 for which we adopt D = 9.2 kpc (Chelovekov & Grebenev 2007).
