Because commissioning work is starting in earnest now, all of the seismic systems have been restored to their nominal configurations. This means ITMX & HAM4 HEPI's were unlocked yesterday after the cleanroom was moved out of the way, all HEPI's and ISIs are back up and running and all sensor corrections (including BRSs) are running on all chambers.

The only difficulty we found was the GS13 gain switching on HAM2 is no longer stable (ie we can't switch GS13 gains while the ISI is isolated). Hugh and I are working with Fil to try to figure that out, but this is a new "feature", we will probably be opening an FRS on it soon.
