Continuing from yesterday's afternoon closeout festivities, this morning Travis and I finished pulling the rest of the HAM2/HAM3 HSTS/HLTS First Contact and spot cleaning the optic edges.  We did the usual N2 top gun blow during and after the pulls.  We double checked tables for extra parts and tools, and finished laying the 3" and 1" witness optics and wafers.  We wiped tables in lots of places.  There are still a few particle-looking spots on some of the HR surfaces but they do not want to move so we had to leave them behind.

While looking at TFs we re-discovered that the PR3 Pitch Transfer Function looked a bit odd, peaks were in the correct place but the signal was steeper in places than expected.  This was due to a broken relay on the BIO chassis.  Fil swapped the unit and things looked better.

Meanwhile, the PR2 Pitch TF also exhibited this and was tracked down to a "stuck" BIO state which was fixed by unplugging and reseating the cable somewhere in the external chain. 

Kissel and Travis are finishing up the suite of TFs for all 6 of these suspensions (IMs were done yesterday 39845), to be posted in a bit.

Jim and Hugh finished ISI floating, balance tweeks, and TFs, logs pending.

Sign-off sheets were completed.  Vern will file to the DCC after the holiday.

Bubba and crew are starting top put doors on, beginning with HAM3 then to HAM2.

Pump down will likely happen early next week after we let the purge air dry things over the holiday weekend.
