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

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)

SOFT Noise and Requirement

HARD Noise and Requirement

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.
