- GRB found by the ground process (failed event data). - DETECTION mask with pcodethresh = 0.01 is used for everything except spectral analysis. - Spectral analysis is not available. - Burst durations are found using quad-rate data from T0_GCN-200 s to T0_GCN+50 s. # No related quad-rate data in the burst folder, thus need to use the pre-made quad-rate data to find burst duration
