1 Noise and Requirement of BRT
Junko Katayama NAOJ / Ochanomizu University 2014/5/21

2 Red line is requirement “1” means noise on QPD1, “2” on QPD2
lateral noises were from seismic spectrum Angular ones were estimated by surface wave Ones caused by lateral motion seem to be not dominant (but not checked strictly yet)

3 SOFT Noise and Requirement

4 HARD Noise and Requirement

5 Conclusion I will check that the angular noises caused by lateral motion are surely not dominant. We can get HARD mode signal. We may be able to get SOFT mode signal if we susped BRT.
