摘要：

We studied the distribution of the peak photon flux ads a function of the spectral hardness tin this paper represented by the hardness-ratio) for the 4B BATSE catalog events. The maximum value of the peak distribution shows, for the first part of the hardness ratio variability range, clear positive correlation with the hardness-ratio up to a given value of the hardness-ratio. On the contrary, for higher hardness-ratio values, an anticorrelation is present. Possible interpretations of these peculiar behaviors are briefly discussed.
