Abstract:

In the new era of gravitational wave astronomy, our primary goal is to measure source parameters and draw astrophysical inferences from observed signals. To do this effectively, we require an accurate calibrated estimate of the gravitational wave strain from our detectors. In this talk, I describe a broad overview of the scheme we use to calibrate the Advanced LIGO detectors, and report on the performance of calibration during the first two observing runs of Advanced LIGO.
