PR3 IAS alignment

Betsy, Travis, Jason

Indeed, things went too well earlier in the week.  This morning we spent a few hours diagnosing why the beam was low on the PR3 after transiting through the PLX (although the PLX assy was level and the incoming IAS beam was verified to be at the correct height).  We finally resolved to pitch the PLX in order to center the beam on the PR3 center and move on.  We then spent many hours this afternoon walking the PR3 pitch everywhere but onto the nominal alignment.  After pouring through some documentation on the HLTS, we discovered the correct knob to turn (not called out well in documentation, and was not obvious to us QUAD-centric folk).  Just as we were back on track, we *ehem* had a bump of the IAS equipment, so we decided to quit and cut our losses.  Long story short, now that Jason will be with us at LHO next week, we will finish up in ~a few hours Monday morning, bright-eyed-and-bushy-tailed.  Sorry, IO, we need one more day!
