Attached below are the snapshots of the transfer function measurements I took yesterday before we kick start the in-chamber work next week. The suspensions look healthy and is currently in air.

The suspensions were set to ALIGNED state after the measurements were complete.
Also, when I logged in on Saturday morning I found the seismic watchdogs of HAM7 chamber to be tripped. I did a reset and sent a text message to Jim. During the measurements the WD tripped again (perhaps due to too much suspension excitation?). I left the ISI to be in damped state.

I had plans to perform similar measurements in HAM6, however this was not possible due to very strong purge air causing the suspensions to saturate (lots of ADC overflows and WD tripping on OM1). There was also an FPU error, which as per Dave was also caused due to the overflows.
I am planning to perform this measurement on Monday morning once the purge air flow is reduced.
