Fits to the stacked X-ray spectra using a power-law (left) and absorbed power-law (right) model. The shaded bands correspond to the 68% range of the posterior. Although stacking improves the constraints on the luminosity, the limited number of counts still results in substantial uncertainty in the spectral shape parameters.
