Comparison of intrinsic X-ray luminosity in the 2−10 keV band estimated by the SED fitting with that from the input catalogue. Green, solid, and dashed lines present the 1:1 correspondence and the errors added in quadrature of the X-ray luminosity calculations from X-CIGALE and those quoted in the X-ray catalogue (Menzel et al. 2016), respectively. The grey dashed line shows the χ² fit of the calculations. Symbols are colour-coded based on their N_H values. Left panel: results with the X-ray flux included in the SED. X-CIGALE calculations are consistent with those from the input catalogue, at all luminosities spanned by our sample. There are 70 sources for which the L_X calculation differs by more than 0.5 dex from their input values (shown with error bars, see text for more details). Right panel: X-ray flux is not included in the SED. In this case, the scatter is significantly larger, while the error of the L_X calculations from X-CIGALE, increases by ≈4×.
