While ZM2, SRM, and SR3 show clean and clear transfer functions as soon as we were out of chamber, the OFI gave us a little scare. All is OK now, but see the story below.
Given Jim's positive assessment of the ISI (LHO aLOG 41313), and now our positive assessment of SUS (this aLOG), 
I conclude that we're ready put doors back on early tomorrow morning.

Again -- excellent work team!!

We took all DOFs for all HAM5 SUS listed above (at a 0.02 Hz resolution) to ensure goodness, and all now appear good. I attach a smattering of the DOFs as proof.

Details of the OFI scare:
The magnitude of all DOFs of the OFI TFs showed a decrease of a factor of 20 or so (see first attachment, blue trace). Knowing we hadn't messed with electronics, a time-machine of the MEDM overview screen made me quickly realize what should have been obvious. The added weight of the new OFI SQZ path picomotor shifted the balance of the OFI in roll enough to completely close-light the OSEMs, so they were barely reading ~hundreds of counts off the ADC when they normally should be centered at ~15k cts. As such, TJ and I quickly ran out to HAM5 again and centered the OSEMs back to ~15k ct off of the ADC. This returned the magnitude of the TFs to normal. There's a bit of fishy-ness happening at around ~1.6 Hz in a ll the TFs, but even if it is cross-coupling because the OSEM's aren't aligned ( in the plane perpendicular to the sensitive axis), that shouldn't matter for the suspended performance. The Qs of the primary resonances look as they did before, and there's no evidence for rubbing there.
