LIGO Document G0900514-v2
- The LIGO detecors are sensitive to a variety of instrumental glitches and environmental disturbances of non-astrophysical origin which increase the false alarm rate in searches for gravitational waves. Using a variety of methods, periods when the interferometers produced data of questionable quality have been identified. We discuss methods used to determine the deliterious times, and the techniques used to safely and effectively veto triggers from the CBC search pipelines during these times; this is done with a minimum loss of science time.
