After lunch we went back to EY to find the mechanical grounding in the ETMy reaction chain.  After a while we spotted a top mass MRB block (hanging part) brushing the tablecloth (structure part).  Our pitch alignment earlier in the day caused the top mass to pitch into the structure.  We could not adjust the structure out of the way* so we adjusted pitch to alleviate the brushing.  The reaction chain pitch has a  ~1.47mRad tolerance and we are still within this at ~860uRad.  Quick low-coherence TFs looked promising so we are restarting the night run full suite Matlab TFs.

*We could not adjust the table cloth easily since 1) everything is suspended - ISI and HEPI included so it all bounces to the lightest touch, 2) the ACB is now mounted and difficult to maneuver around, and 3) the table cloth serves purpose for both chains simultaneously so adjusting it for one chain somewhat anti-adjusts it for the other chain - too risky at this point.
