• Advantages
• Wide FOV ? observe many bright GRBs,
• Wide Energy Range with detectors of the same
  type.
• GRB Selection Criterion
• 50 to 300 keV Fluence gt 2.5E-5 ergs cm2,
• Observed with both high-gain and low-gain SD,
• Data coverage for gt? 80 of the fluence,
• High-gain SD has source angle lt 80?,
• Low-gain SD has source angle lt 60?.
