The excess-power method is a Fourier-based time-frequencymethod to search for gravitational wave bursts. The implementationuses time-frequency planes at multiple resolutions and computes power intiles defined by a start-time, duration, central frequency, andbandwidth. We discuss the behavior of the search method on real data, outline studies of its sensitivity, and coincidence criteria used in acoincidence search.
