- Burst duration shorter than 0.05 s (minimum time bin for mosiac image), hence reset T100_stop to T100_start+0.05 for making mosaice image. - GRB found by the ground process (slew event data). - Refined positions found by mosaic image (DETECTION mask with pcodethresh = 0.01, time bin = 0.05 s, and energy band = 15-350 keV). - Possible GRB. # single-ish pulse GRB.
