Top panel: unfolded phase-averaged spectrum of Obs. II with the best-fit model: XRT (gold), FPMA (blue), FPMB (red), and model (black). All models include an additional narrow iron line. The gray line shows a decomposition of the CutoffPL and the Gaussian component. Lower panels: residuals to the different continuum models. For clarity we binned the spectra using larger bins for the plot than the ones used for the fit.
