I ran long tfs on HAM3 overnight, given the state it's in (hepi locked, in air) tfs look good. Attached plots show  cartesian tfs for GS13s and CPS. Main resonances look clear, all the high frequency (>10hz) crap is from HEPI being locked (I think, it looks worse on the CPS, which is what we've seen in the past). Cabling on the east side looked pretty messy, but doesn't seem to have been a problem.
