Notes. We model the X-ray and optical light-curve with a two-component function: an initial power-law (PL) plus a late-time broken power-law (BPL). Here we report the initial power-law decay (αPL), the rising (αBPL,rise), the break time (tbreak), the peak time (tpeak), and the decaying index (αBPL,decay) of the second component. The last column shows the goodness-of-fit (reduced χ2) and the corresponding degrees of freedom.
