Top: E²f(E) unfolded spectra of 1E 1547.0–5408 extracted from the merged NuSTAR data sets at the maximum (in black) and at the minimum (in red) of the pulse profile. Data points were re-binned for plotting purpose. The solid lines represent the best-fitting BB+2PL model. Dashed lines mark the contribution of the single components to the spectral model. Bottom: post-fit residuals in units of standard deviations.
