Comparison between the 2−10 keV flux estimated by Xamin 3.3 assuming a power-law spectrum with Γ = 1.7, NH = 2.6 × 1020 cm-2, and the spectral fit value (grey points). The black line shows the one-to-one relation. The open squares denote the sources that have low-quality X-ray spectra, (flag = 4, see Table 2).
