Abstract

The Laser Interferometer Gravitational Wave Observatory (LIGO) is a network of three detectors built to detect local perturbations in the space-time metric from astrophysical sources These detectors two in Hanford WA and one in Livingston LA are power-recycled Fabry-Perot Michelson interferometers In their fifth science run (S5) between November 2005 and October 2007 these detectors accumulated one year of triple coincident data while operating at their designed sensitivity In this paper we describe the calibration of the instruments in the S5 data set including measurement techniques and uncertainty estimation.
