Notes. All times are in seconds after the start of the burst, unless noted otherwise. (a)From ∼20 s to ∼300 s the light curve is flattened. If the exponential function is fitted to the light curve after this flat phase, the e-folding time decreases significantly to 130.37 ± 31.35 s. More information in Sect. 4.7.
