Fig. 2
Extrapolation down to 0.3 keV of the fit over the 3–10 keV energy range of the four 2014 XMM-Newton/pn spectra with the baseline relativistic reflection model (model 
), where q is allowed to vary and Rin is fixed to the ISCO. The fit parameters are reported in Table 2 (Col. 2). Black: March 18, red: March 20, green: March 22, and blue: March 24.
