Abstract: Amplitude calibration procedures have been developed by the LIGO Scientific Collaboration (LSC) for use in determining the strain sensitivity of the three LIGO interferometers. These frequency-domain procedures rely on a fiducial calibration taken at a reference time t0. The calibration is then propagated to all other times during the science run via calibration factors (denoted by and ), which are derived from sinusoidal length excitations in interferometer cavity lengths. We briefly review the standard calibration methods that were employed in the first two LIGO science runs (S1 and S2), and then describe improvements in calibration procedures implemented during the third science run S3.
