Because the Hartman WFS alignment was going to need the ITMx optics free of FirstContact, we pulled it yesterday.  However, we first re-re-removed the QUAD sleeve structure and the 4 vibration absorbers which are in the way of the pitch alignment due to take place today.  Also prior to removing the FC, we also found high particle counts in the ITMx chamber.  Hugh played around with purge (again) and we closed up the small IAS window at the spool.  This seemed to improve things a bit.  After taking data on particle counts for a while, we proceeded to pull the FC anyways knowing that we'll have to reclean the optic befor chamber close up.
