X-ray model parameter evolution over the orbital phase using the NuSTAR data. The different colors indicate different orbits during the ~20 ksec exposure: blue corresponds to the first, light blue to the second, and green to the third orbit. From top to bottom: the hydrogen column density, optical depths of the neutral and helium-like iron, bolometric blackbody luminosity assuming a distance of 7.4 kpc, fraction of Compton upscattered seed photons, and unabsorbed blackbody and Comptonized fluxes calculated from the NuSTAR energy band 3–79 keV are shown.
