Attached are uncalibrated spectra from the new TT(Table Top[sic]) L4C that are actually inside the Optics Table, not on top of the table.  The reference, thick traces are before unlocking HEPI and the current traces are with HEPI off the stops and Robust Isolated.  All the RMs are damped/aligned.

EE (Ed) is cabling up the ISCT1 so the current spectra may show some activity.  It looks like the V1 sensor may have an issue below about 400mHz as it does not follow its sisters lower when isolated.  V2 also has some noise around 1Hz.  Likewise, not sure why the H1 sensor gets worse after Isolating below 200mHz.  The H1 also has some noise around 20Hz.
