Studies of BATSE bursts (Kouveliotou et al. 1993) have resulted in the widespread adoption of a two-group categorization: long bursts (those with durations ≥2 seconds) and short bursts (those with durations ≤2 seconds). This categorization, one must recall, used the observed T ₉₀ time durations for bursts (during which 90 % of a burst's fluence is measured).
