Abstract:
    A comprehensive temporal analysis has been performed on the 319
    brightest GRBs with T_90_>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.
