  • 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)



Hard noise and requirement
HARD Noise and Requirement


Conclusion
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.
