Notes. The first 25 bursts are the ones for which a power-law model was enough to describe the light curve behaviour (PL subsample). The last 15 bursts are the BPL subsample, for which the addition of a break resulted statistically significant (see Sec. 3.2). The (F) marks the cases for which a flaring component was discarded to allow a better fit of the afterglow.
