CorrPower is a cross-correlation-based algorithm to be used in the LIGO burst analysis. The code looks for excesses of coherent power in multiple interferometers, unifying techniques previously implemented in the LIGO triggered and untriggered burst searches. CorrPower performs three functions: (1) a continuous scan of the data, (2) an r-statistic waveform consistency test on candidates produced by the burst event analysis (Cadonati L 2004 Class. Quantum Grav. 21 S1695 703, LIGO Scientific Collaboration 2005 Preprint gr-qc/0505029), and (3) a search around the time of external triggers, a natural evolution of the analysis used for the gravitational-wave signature of GRB030329 (LIGO Scientific Collaboration 2005 Phys. Rev. D 72 042002, Mohanty S et al 2004 Class. Quantum Grav. 21 S1831 7, Mohanty S et al 2004 Class. Quantum Grav. 21 S765 74). The paper describes the techniques implemented in the continuous data scan and presents its expected performance on simulated data from two or three ideal detectors with white Gaussian noise.
