Coincidence analysis to search for inspiralling compact binaries

We discuss a method of coincidence analysis to search for gravitational waves from inspiralling compact binaries using the data of two laser interferometer gravitational wave detectors. We examine the allowed difference of the wave's parameters estimated by each detector to obtain good detection efficiency. We also discuss a method of setting an upper limit to the event rate from the results of the coincidence analysis. For the purpose of testing the above methods, we performed a coincidence analysis by applying these methods to the real data of TAMA300 and LISM detectors taken during 2001. We show that the fake event rate is reduced significantly by the coincidence analysis without losing real events very much. Results of the test analysis are also given.
