Grabbed a few closeout measurements of H1 SUS OMC. All clear; good to go for door closure.
Transfer functions show that the dynamics are virtually identical to what they were before. See

High Frequency OSEM sensor noise ASD,
- 2018-04-26_1831_H1SUSOMC_M1_OSEM_Noise_ASDs.png
has some spikes, but nothing egregious like a grounded BOSEM (e.g. LHO aLOG 40787). If I had to complain, I would complain about the T1 OSEM being a little higher in noise starting around 500 Hz. But I don't have to complain, so I won't. #WORKSFORME
