LIGO Seminar

Advanced LIGO Calibration Uncertainty for Precision Astrophysics
Craig Cahillane, LIGO, Caltech)

Calibration of the Advanced LIGO detectors is the characterization of the

detectors' response to gravitational waves. Understanding the detector

calibration is crucial to accurately and precisely produce gravitational

wave strain data. Estimates of binary black hole parameters like total

masses, distance, and sky location directly depend on the accuracy and

precision of calibrated data. Tests of general relativity also rely on

properly calibrated data, as miscalibrations could be degenerate with

deviations from GR.  Quantifying the detector response, response

uncertainty, and producing calibrated strain data is the role of the

calibration group.  We describe the method of producing calibration

uncertainty budgets for both LIGO detectors in the first and second

observation runs.

 
We plan to broadcast these talks using TeamSpeak. Use a sub-channel of

LIGO Lab called "LIGO Seminar", which is not password protected.

NOTE: These and all other scheduled LIGO seminars are listed on the LIGO
Laboratory seminar calendar for convenient reference.
