Abstract:

These are calibrated strain and displacement spectra from a representative lock stretch for the beginning of O1, taken on Oct 01 2015, when the inspiral range was 72 Mpc.

Though the calibration must be tracked over time for changes at the 20% level, the uncertainty in calibration at this time is 10% and 5 [deg], valid between 10 and 2000 [Hz] (the uncertainty is larger and unquantified outside this band). For details see LHO aLOG 21689,

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

For details on how the ASD was calculated, see T1500365.
