| Abstract: |
We used Kaplan-Meier (KM) survival analysis to study the true distribution of high energy (F4) fluences on BATSE. The measured values were divided into two classes: A. if F4 exceeded the 3σ of the noise level we accepted the measured value as "true event." B. WE treated 3σ as an upper bound if F4 did not exceed it and identified those data as "censored." KM analyses were made for short (y90 < 2s) and long (y90 < 2s) bursts, separately. Comparison of the calculated probability distribution functions of the two groups indicated about an order of magnitude difference in the > 300 keV part of the energies released. |
