Scientific paper

We have performed a global study of gamma-ray burst spectra using the moderate time and energy resolution CONT data from BATSE. These data have 2 s temporal resolution in 16 energy channels that span the range of approximately 20 keV to 1.8 MeV. Spectral fits were created for a large ensemble of gamma-ray bursts. We present distributions of the peak energies in νν, and discuss the burst hardness-intensity correlation. To analyze this correlation, bursts must be ranked according to their intensity. We have investigated the effect of how the intensity definition influences the resulting correlation by using the peak flux on several timescales as the definition of burst intensity. It is shown that longer timescales tend to weaken the hardness-intensity correlation, although the correlation remains for all definitions of intensity that were examined, and is consistent with the effect expected from a cosmological distribution of gamma-ray bursts.
