Left: X-ray spectral fits (unfolded model and residuals) for the X-ray detected DOGs in our sample. Filled circles and empty squares correspond to Chandra and XMM-Newton data, respectively. Middle: comparison between the confidence contours for the column density values computed for the 4 Ms data (dashed line) and 6 Ms data (solid line). The horizontal dotted line indicates the 90% confidence level. Right: SED fits for our X-ray DOGs sample. Solid line: full model; dotted line: AGN contribution; dash-dotted line: stellar contribution; and dashed line: starburst contribution. Our Compton-thick candidates are sources 95, 230, and 309.
