Gamma ray bursts and gravitational waves: triggered search strategy in the LIGO science runs

We describe a complete analysis pipeline for detecting and estimating gravitational wave signals in conjunction with observations of astrophysical phenomena with an electromagnetic or particle signature, examples of such phenomena being gamma ray bursts (GRB) and supernovae neutrino bursts. Our data analysis methods explicitly account for non-Gaussian and nonstationary features in real interferometric data. This pipeline is meant for signal searches in conjunction with individual GRB triggers and is being used for the analysis of data from the LIGO science runs (S1 and S2). However, many aspects of the pipeline are quite general and can also be used for other broadband interferometric detectors.
