These are calibrated strain and displacement spectra from a representative best of O3a, taken on Apr 29 2019, when the luminosity range for 1.4-1.4, 10-10, and 30-30 [M_sol] binary systems was 135.7, 657.4, and 1136 [Mpc], respectively.

These spectra are in the process of being reviewed and should be considered preliminary and are subject to change in future versions.

This data is from that regenerated offline to account for data dropouts and has been compensated for time-dependence in the detector response ("C01," DCS frames in LIGO jargon). The data has been processed to subtract the linear noise contributions from calibration lines and 60 Hz line. Further, the linear, non-stationary noise around the 60 Hz line has been subtracted using the NONSense method (P1900335). We expect the uncertainty in calibration at this time 5% and 3 deg [deg], valid between 10 and 2000 [Hz] (the uncertainty is larger and unquantified outside this band).

The code that produced this plot can be found via T1500365
