This morning, before anyone got on site to complain about it, Hugh and I unlocked HEPI on HAM1. We then turned on the isolation loops we installed last night. Everything turned on as (un)expected, we were able to steer then table back close to where it was. In addition, sensor correction in Z from the ground STS2 under HAM2 works as well, meaning we get a little inertial isolation below 1hz, something like a factor of 10 at .2hz. Attached plot shows HEPI L4C spectra of 3 states, blue is locked this morning, green is unlocked/isolated, red is isolated with sensor correction. There is probably some contamination from a few hz to 30 hz from Kyle's pump cart (almost touching one of the piers!) and other activites in the LVEA. Or at least I hope that's what explains the big peak at 2-3 hz.
