- Only part of the event data are used in order to have a more reasonable estimation of burst durations. When including data after ~T+550s, the 16ms binned light curve keep getting T100 ~ 530 s (while other binned get more reasonable durations). The background looks find, my guess is that there is a glitch somewhere between T0+500 to T0+530 s, need to check this later. # single-ish pulse GRB.
