摘要 | We have studied the total fluence, F-total, as a function of the hardness ratio, HR32, on gamma-ray bursts (GRBs) observed by BATSE, and suggested two subsets of bursts divided by division of log (F-total) = 4.5 x log (HR32) - 8.5, then investigated correlations between HR32 and F-total as well as the distributions of the duration, T-90, and HR32 in the two subsets. The results show that F-total is not correlated with HR32 in the entire set of GRBs, while it is in the two subsets, and the division statistically coincides with the division of T-90 similar to 2 s. A brief discussion along with the results seems to support the point that the anti-correlation between HR32 and T-90 is intrinsic. |
