Evolution of the power law photon index (top), the inner disk temperature T_in (middle) and the power-law and disk flux (bottom, filled and empty circles respectively) in the 3−25 keV energy band in units of 10^-10 erg cm^-2 s^-1. The black symbols are the results of this campaign while the gray ones have been obtained by Dinçer et al. (2012). The model used is tbnew× (diskbb+ power law + gaussian) in the 0.7−10 keV range.
