Spectrum of 1E 1547.0–5408 extracted over the 0.7–70 keV energy band from the Swift XRT (black triangles) and merged NuSTAR data sets (red circles). Data points were re-binned for plotting purpose. The solid line represents the best-fitting BB+2PL model. The E²f(E) unfolded spectrum is shown in the middle panel. Dashed lines mark the contribution of the single components to the spectral model. Post-fit residuals in units of standard deviations are shown in the bottom panel.
