Notes. We have split the 91 test sources into four classifications based on their X-ray-measured column densities: CT (Log(NH) > 24), Compton-thin (23 < Log(NH) < 24), obscured (22 < Log(NH) < 23), and unobscured (Log(NH) < 22). The numbers of sources correctly classified for each of the four methods mentioned in this paper are shown below.
