WBSC1/ITMY ISI Adjustment Completed--Things look Good
Jim & I moved one stack of the Trim Mass & Damping Assemblies (D1003161) 5" +Y.  Next we removed 0.75kg from each of two Assemblies to compensate for the strut that SUS has added to the Quad.  These two Assemblies are located at A27,B48 & A36,B48 (D1001989 sht3.)

At this point, Travis came into the chamber and removed the SUS protection pieces and the IAS CornerCube; he did not remove the Teflon Stops and the SUS remains locked.
Next, Jim unlocked Stage2 and the CPS numbers settled down suggesting that when the Teflon Stops are removed, all corners will look pretty good.  Corner 1 is a little low and removing those stops should lift that side of Stage2.  Then Jim unlocked Stage1 and the CPS numbers look comfortably close to the pre/vent & ISI lock time at the start of the year.

So next step is to back off the HEPI locks--they are very lightly engaged.  Check the optical table level.  Have IAS check X position, adjust as required with HEPI.  Unlock the SUS and check pitch & yaw; adjust as required.
