Log NH versus F2 − 10 keV/F20 − 100 keV flux ratio for our sample sources. Open circles are Seyfert 1–1.5 sources, while filled circles are Seyfert 2 sources. Triangles are blazars, filled squares are XBONG, and stars are LINERs. As in Malizia et al. (2007), lines correspond to the expected values for an absorbed power law with photon index 1.5 (dotted line) and 1.9 (dashed line).
