The NICER (green), Resolve (black), and NuSTAR (blue and red) unfolded spectra (top) and data-to-model ratios (bottom) for the fit with two reflkerrD components. The total and unabsorbed model spectra are shown by the solid black and cyan curves, respectively. The incident and reflection components are shown by the blue and red curves for the hard component and by the green and magenta curves for the soft component, respectively. The unscattered disk component is shown by the brown curve.
