The log N(>P)- log P Distribution of γ ray Bursts

WU Mei SONG Li ming YU Wen fei LI Ti pei LI Yi( Institute of High Energy Physics, Cosmic Ray and High Energy Astrophysics Lab, The Chinese Academy of Sciences )  
Assuming that the bursts have identical peak fluxes, i.e. the“standard candle” hypothesis is valid,and have also identical density, the log N(P) ~log P distribution of γ ray bursts isanalyzed using the simple cosmological model. There is no significantdeviation between the theoretical result obtained from the cosmological modeland BATSE data corrected for trigger efficiencyand dead time.
