- T100, T90, and T50 are lower limits. The burst duration is longer than the event data. This burst has been previouly classified as an ultra-long GRB (e.g., Gendre et al. 2013). - The event data are only available for part of the burst duration. - Spectral analysis is only available for part of the burst duration. - battblocks failed because of the weak nature of the burst. The burst does not show significant structure in the light curve, hence battblocks fails to find burst durations. Use the whole available event data range (from 161926415.404000 to 161926775.040000) to make the T100 spectrum - The 1s-peak spectrum and time-resolved spectra are unavailable because battblocks fails.
