Gamma-Ray Burst Prompt Correlations

Figure 6

The average peak energies as a function of intensity for five groups of GRB spectra. The vertical bars represent estimated error in the mean, where the peak energy distributions were assumed to be approximately Gaussian in logarithm of energy. The horizontal bars mark the bin widths.
