X-ray light curves for different set of parameters corresponding to the points from 1 to 4 (bottom to top) marked in Fig. 5. The first break of the X-ray light curves 1 and 2 occurs at around 125 s, while for the light curves 3 and 4 occurs later at t ~ 650 s. For clarity reasons, light curves 1, 3, and 4 are plotted with an offset of  −0.2,  +0.4 and  +0.5 in logarithmic units of flux.
