Virgo is a kilometer-length interferometer for gravitational waves detection located near Pisa. Its first science run, VSR1, occured from May to October 2007. The aims of the calibration are to measure the detector sensitivity and to reconstruct the time series of the gravitational wave strain h(t). The absolute length calibration is based on an original non-linear reconstruction of the differential arm length variations in free swinging Michelson configurations. It uses the laser wavelength as length standard. This method is used to calibrate the frequency dependent response of the Virgo mirror actuators and derive the detector in-loop response and sensitivity within ~5%. The principle of the strain reconstruction is highlighted and the h(t) systematic errors are estimated. A photon calibrator is used to check the sign of h(t). The reconstructed h(t) during VSR1 is valid from 10 Hz up to 10 kHz with systematic errors estimated to 6% in amplitude. The phase error is estimated to be 70 mrad below 1.9 kHz and 6 micro-seconds above.

Sensitivity Limits and Operational Threshold Calibration for DINOv2-based Gravitational-Wave Glitch Characterization: A Strain-Domain Mock Data Challenge on LIGO O4a
Is GW151226 a really signal of gravitational wave?
最近，LIGO科学合作组织和Virgo合作组织发表了对引力波GW 151226的第二次观测[Phys. Rev. Lett. 116，241103（2016）]来自初始质量约为14 M $_\odot$和8 M $_\odot$的双黑洞合并。他们声称，峰值引力应变在大约450 Hz时达到，其倒数比光子在两臂法布里-珀罗腔中停留的平均时间更长。在这种情况下，由于引力波的传播，光子在两臂中的相位差并不总是随着光子在腔中的停留而增加。在极端情况下，它甚至可能被取消为零。当考虑到传播效应时，我们发现要求保护的信号GW 151226几乎消失。
