Fitting results to the combined XIS and HXD spectra of the outburst and quiescent states in the 1.0–30.0 keV band (a-1, b-1). Panels (a-2) and (b-2) are magnifications of the 5.0–9.0 keV band, showing the iron line spectra. Black, red, green, and blue are used for XIS 0, XIS 1, XIS 3, and HXD, respectively. The third rows of panels (a-2) and (b-2) show the data residuals from the model with the normalization of the lines being set equal to zero. The significance of the lines is 8.0 σ and 4.8 σ for outburst and quiescence, respectively. (Color online)
