Results of the search for inspiraling compact star binaries from TAMA300’s observation in 2000–2004

We analyze the data of the TAMA300 detector to search for gravitational waves from inspiraling compact star binaries with masses of the component stars in the range $1{M}_{\ensuremath{\bigodot}}--3{M}_{\ensuremath{\bigodot}}$. In this analysis, 2705 hours of data, taken during the years 2000--2004, are used for the event search. We combine the results of different observation runs, and obtain a single upper limit on the rate of the coalescence of compact binaries in our Galaxy of 20 per year at a 90% confidence level. In this upper limit, the effects of various systematic errors such as the uncertainty of the background estimation and the calibration of the detector's sensitivity are included.
