GEO 600 is an interferometric gravitational wave detector which, when completed, will employ a novel, dual-recycled optical scheme allowing its optical response to be tuned over a range of frequencies. The accurate calibration of the sensitivity of GEO to gravitational waves is a critical part of preparing GEO data for exchange with other detectors worldwide and for the extraction of scientific results. The final optical scheme that will be used in GEO will make it necessary to combine more than one output signal to optimally recover a calibrated strain channel. An on-line calibration scheme has been developed with a view to covering both the power-recycled and dual-recycled interferometer configurations of GEO. The recent worldwide coincident science run (S1) proved an excellent opportunity to test the calibration scheme of GEO in a power-recycled mode. The ability to track and study the stability of the calibration over long time scales was invaluable. A number of areas have been highlighted where impro...
