1 When the photon index is fixed to 1.8 the spectral fittings are performed using the C-statistic technique. 2 Observed, best fit $N_{\rm H}$ value in units of 1022 cm-2. 3 Intrinsic 2-8 keV flux in units of $\rm 10^{-14}$  $\rm erg~cm^{-2}~s^{-1}$. 4 Galactic column density in the directions of the observed field in units of 1020 cm-2. 5 Intrinsic rest frame column density in units of 1022 cm-2. 6 Logarithm of intrinsic 2-8 keV luminosity in units of  $\rm erg~s^{-1}$. 7 The ID values (ID = 1, 2 or 3) indicate spectroscopic, photometric or the absence of an optical counterpart respectively.
