    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 non-stationary and non-Gaussian artifacts. We provide details on the methods used in the findchirp algorithm as used in the search for sub-solar mass binaries, binary neutron stars, neutron star--black hole binaries and binary black holes.

    ABSTRACT: All three LIGO gravitational wave detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for gravitational waves emitted from inspiral binary neutron stars with masses of 1.4 M has been achieved with the two 4 km instruments. The fifth LIGO science started in November 2005 and ended in September 2007. A full year of triple coincidence data has been acquired. The duty cycle of a single instrument was between 66% and 79%. Results from previous science runs are presented.

    ABSTRACT: All three LIGO detectors have reached their design sensitivities. A sky-averaged detection range (SNR > 8) of more than 15 Mpc for inspiral binary neutron stars with masses of 1.4 Msol has been achieved with the two 4 km instruments. The fifth LIGO science started in November 2005 and ended September 2007. About 365 days of coincidence data have been collected. The feedback controls system is a major component to make LIGO work and its performance has been crucial to achieve the present sensitivity.
