FINDCHIRP: an algorithm for detection of gravitational waves from inspiraling compact binaries

摘要

Matched-filter searches for gravitational waves from coalescing compactbinaries by the LIGO Scientific Collaboration use the FINDCHIRP algorithm: animplementation of the optimal filter with innovations to account for unknownsignal parameters and to improve performance on detector data that hasnonstationary and non-Gaussian artifacts. We provide details on the FINDCHIRPalgorithm as used in the search for subsolar mass binaries, binary neutronstars, neutron star-black hole binaries, and binary black holes.
