Abstract

We analyze the evolution of BATSE GRB continuum spectra using the BATSE Spectral Analysis Software. We check the consistency of various methods used to characterize spectral hardness: hardness ratio, single power law index, OTTB temperature, and break energy of a broken power law fit. Time evolution of spectral parameters is compared with derived energy fluxes. We also search for correlations between the different spectral parameters and derived quantities, such as break energy, power law indices above and below the break, and energy flux.
