Gamma-ray bursts Have a wide range of temporal properties.
The figure below shows the distribution of durations of the bursts observed
by BATSE on CGRO:
The two different lines represent different definitions of the start and end
(and hence duration) of the burst.
BATSE Gamma-Ray Burst Sample Time Histories
Three sample time histories are shown for gamma-ray bursts detected by BATSE.
Each burst has its own unique time signature.
Some are very irregular and spiky.
Others are smoothly varying.
