ITMY QUAD status

Yesterday, Travis found the mechanical rubbing point on the ITMY - we ran a few short TFs and things look much more suspended.  The beam still is on the oplev, I made some small bias adjustments to center it up, but we should be ready for a full suite of TFs as only cleaning is left to do on this unit, which won't happen until closer to closeout.

Note, my new slider values for centering on the OPLEV are

P = -67

Y = -183

Recall, these values are still in the ballpark of the IFO aligned values which we haven;t touch much except to repoint for reference due to the venting of the chambers.

This sus has been hanging damped and aligned overnioght in air and should stay this way until notified otherwise (cleaning, ISI rebalancing in a few weeks).
