- GRB found by the ground process (failed event data). - The event data are only available for part of the burst duration. - Spectral analysis is only available for part of the burst duration. - Burst durations are found using quad-rate data from T0_GCN-200 s to T0_GCN+70 s. - Though almost all of the event data happen during slew (starts from T0+0.3s), the image seems okay. So I didn't make a mosaic image to find the refined position.
