Descripción
We report on the first joint search for gravitational waves by the TAMA
and LIGO collaborations. We looked for millisecond-duration unmodeled
gravitational-wave bursts in 473 hr of coincident data collected during
early 2003. No candidate signals were found. We set an upper limit of
0.12 events per day on the rate of detectable gravitational-wave bursts,
at 90% confidence level. From software simulations, we estimate that our
detector network was sensitive to bursts with root-sum-square strain
amplitude above approximately
1-3×10-19Hz-1/2 in the frequency band
700-2000 Hz. We describe the details of this collaborative search, with
particular emphasis on its advantages and disadvantages compared to
searches by LIGO and TAMA separately using the same data. Benefits
include a lower background and longer observation time, at some cost in
sensitivity and bandwidth. We also demonstrate techniques for performing
coincidence searches with a heterogeneous network of detectors with
different noise spectra and orientations. These techniques include using
coordinated software signal injections to estimate the network
sensitivity, and tuning the analysis to maximize the sensitivity and the
livetime, subject to constraints on the background.
