Statistical-Uncertainty-Driven Selection of Evaluation Frequency for Time-Dependent Sensing Calibration: A Demonstration with KAGRA Data
Shingo Hido, Takahiro Yamamoto, Dan Chen +2
Accurate calibration of the gravitational-wave strain h(t) is essential for both detection and astrophysical inference. In operating detectors, slow temporal variations in the sens…

Statistical Estimation and Correction of Model-Measurement Bias in Time-Dependent Correction Factors of KAGRA
Shingo Hido, Takahiro Yamamoto, Dan Chen +2
Calibration of gravitational-wave detectors reconstructs the strain h(t) from the detector output, and bias and uncertainty in this reconstruction directly affect downstream analys…

Photon Calibration Performance of KAGRA during the 4th Joint Observing Run (O4)
Dan Chen, Shingo Hido, Darkhan Tuyenbayev +9
KAGRA is a kilometer-scale cryogenic gravitational-wave (GW) detector in Japan. It joined the 4th joint observing run (O4) in May 2023 in collaboration with the Laser Interferomete…
