High EY vibration coupling

Tonight we were able to shake at EY after finishing EX last night. We found the EY vacuum enclosure to couple much more to DARM than the EX enclosure, and more than during O2. The Figure shows that factors of 10 increase in motion (which happens between 4 and 12 Hz when big trucks pass on 240), produce large scattering features in DARM. More later.
