Print this reportGround motion and SR3 chamber vibrationThis morning, the ground motion of human activity appeared again, then the peaks around 80 and 100 Hz appeared in DARM sensitivity.
Because yesterday, we prepared the portable PEMs around SR3 chamber, I checked the signal.
Some signal appeared in 8 an 9 Hz in accelerometers. Some up conversion happened?
