Noises and RequirementBRT 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)
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.
