- battblocks failed because of the weak nature of the burst. The burst is weak and the light curve does not show obvious structure, thus battbleck failed to find burst duration. Use T0 to T0+320 s (the image trigger period) to calculate the T100 spectrum.

- The 1s-peak spectrum and the time-resolved spectra are also unavailable because battblock fails.

- T100, T90, and T50 might be lower limits. It is hard to tell when the burst ends due to the large statistical error (GCN 8390).
