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

Creators: Allen, Bruce; Anderson, Warren G.; Brady, Patrick R.; Brown, Duncan A.; Creighton, Jolien D. E.

Abstract

Matched-filter searches for gravitational waves from coalescing compact binaries by the LIGO Scientific Collaboration use the FINDCHIRP algorithm: an implementation of the optimal filter with innovations to account for unknown signal parameters and to improve performance on detector data that has nonstationary and non-Gaussian artifacts. We provide details on the FINDCHIRP algorithm as used in the search for subsolar mass binaries, binary neutron stars, neutron starblack hole binaries, and binary black holes.
