Data/model ratios for the XMM-Newton (black: EPIC-pn, red: EPIC-MOS), Suzaku (green: FI XIS, blue: BI XIS), and NuSTAR (magenta: FPMA, cyan: FPMB) data sets obtained during epoch 1, modeled with both a power-law continuum (top panel) and a bremsstrahlung continuum (bottom panel). The data from the various missions display consistent curvature across their common energy range (3–10 keV). The data have been rebinned for visual clarity.
