Top panel: broad band X-ray spectrum of 2S 1845−024 extracted from Swift/XRT (green crosses) and NuSTAR/FPMA and FPMB (red and black crosses). The solid blue line represents the best-fit model CONSTANT × TBABS × (PO × HIGHECUT + GAU). Bottom panel: residuals from the best-fit model in units of standard deviations. We emphasize that the Swift/XRT spectrum is obtained in the range 0.3−10 keV; however, there are not enough soft X-ray photons below 3 keV because the spectrum is highly absorbed.
