XMM-Newton EPIC-pn spectra of PG 1126-041 extracted in the 0.3 − 10 keV band in eight different epochs of observation. Left panel: spectra unfolded against a power law with Γ = 2. Right panel: spectra of each epoch unfolded against a Γ = 2 power-law model are plotted individually over the 2009 spectrum as a reference.
