We describe a coherent network algorithm for detection and reconstruction of gravitational wave bursts. The algorithm works for two and more arbitrarily aligned detectors and can be used for both all-sky and triggered burst searches. We describe the main components of the algorithm, including the timefrequency analysis in a wavelet domain, construction of the likelihood timefrequency maps, and identification and selection of burst events.

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs (2018, background): “Designed to operate without a specific waveform model, cWB identifies coincident excess power in the multiresolution time-frequency representations of the detector strain data [85], for signal frequencies up to 1 kHz and durations up to a few seconds.”
Tests of general relativity with the binary black hole signals from the LIGO-Virgo catalog GWTC-1 (2019, methodology): “This cWB search [15, 36, 37] was tuned to detect chirping signals—like those that would be expected from compact binary coalescences—but was not tuned to any specific GR predictions.”
