- GRB found by the ground process (failed event data). - The event data are only available for part of the burst duration. - 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+100 s. # Remake quad-rate lc using pre-made quad-rate data, and cut lc to T0-200s to T0+100s.
