Today, we finished tuning the 12 DOFs of the ETMy QUAD.  We had to take some time evaluating the gap laser measurement system as it turns out that it is very sensitive to it's own level.  In the end, all 12 DOFs are within tolerance.  All lower stage OSEMs are aligned and looking at 50% OLV flag/sensor positions after we played a few rounds of the alignment game with them.  Note, there is some differential roll between the main and reaction chains which made aligning the lower stage OSEMs additionally difficult.  This is likely because there is some wire segment at the wrong length or some mass assymetry somewhere - it has been like this since the y-arm OAT as an H2 suspension, so we are just hoping for clean TFs again.  It is very invasive and time consuming to swap wire segments at this point so we'll just see what the TFs show in the morning*.  Arnaud has started running TFs now.
