Abstract:
A comprehensive temporal analysis has been performed on the 319
brightest GRBs with T90>2s from the BATSE (Cat. IX/20) current
catalog. The GRBs were denoised using wavelets and subjected to an
automatic pulse selection algorithm as an objective way of
identifying pulses and quantifying the effects of neighbouring pulses.
The number of statistically significant pulses selected from the
sample was greater than 3000. The rise times, fall times, full-widths
at half-maximum (FWHM), pulse amplitudes and pulse areas were measured
and the frequency distributions a represented here. All are
consistent with lognormal distributions provided the pulses are well
separated.
