Time evolution of the different fit parameters. From top to bottom: the hot corona temperature kThc, Compton parameter yhc, optical depth τhc, and the warm corona temperature kTwc, photon index Γwc, optical depth τwc, and the soft photon temperatures Tbb,wc and Tbb,hc. The solid lines show the best-fit constant values and the solid lines the ± 1σ uncertainties.
