Abstract:

Estimated sensitivity for O3 in case of different IFO configutations with 10W, including the shot noise coupling with feedforward gain of 100.
IFO configurations considered here are:
- FPMI with tilted PRM (equivalent to 1W input power)
- FPMI with blank PRM
- PRFPMI (R_SRM=0 %)
- RSE with R_SRM=70 %
We also consider four excess noise models:
- No excess
- aLIGO O1 level
- 4x aLIGO O1 level (AdV O2 level)
- 8x aLIGO O1 level
