Spectral models computed with the uxclumpy code described in (Buchner et al. 2019) rescaled to the observed 10–30 keV flux from the stacking analysis. We refer to the text for details on the model assumptions and geometry. The column density increases from 5 × 10²³ cm⁻² (red curve) to 2 × 10²⁴ cm⁻² (blue curve) and 10²⁵ cm⁻² (cyan curve). The UHB detection and the upper limits in the SB and MB are also reported.
