A measurement of the direct CP asymmetry between inclusive b→sγ decays was performed. It was observed that this asymmetry was expected to be less than 0.01 in the standard model but could be enhanced up to 0.10. The different components of the signal and background events was also identified that was described by a crystal ball function. Monte Carlo simulations were also applied to the four contributions to the beam energy substituted mass distribution of events.
