Caption: Figure 5.

Bolometric unabsorbed flux from time-resolved spectroscopy, where the shaded bands indicate the 1σ error regions. Top: fit with scaled pre-burst component shows this part to increase during the burst (dotted line indicates the pre-burst flux level). Bottom: alternative fit with reflection model. The vertical dotted line demarcates the two fitted intervals of the peak and tail.
