WBSC3 ITMx HEPI Moves for IAS & now locked for ACB

As Jason logged yesterday, the ITMx was good except for the Yaw.  SEI turned the HEPI DSCW Springs to correct the Yaw error; we brough it from 1.6mrad to 35urads.  We then checked and leveled the Optical Table.  It was only barely out of spec with 0.3mm over the table; we got it to <0.2mm just hitting our 100urad goal.  With the Optical Level using TGT402 for reference, the OT is 0.6mm high.  I locked the HEPI after final DI readings for ACB work.

With these Yaw and Level adjustments, some unintended motion occur but they are small.  Based on the Dial Indicators, the platform moved 0.1mm South, 0.2mm East, & 20urads CW since the observations IAS took. We should be in OK shape.

Attached find my log book pages for this saga.  Thanks, to GregG & MitchellR
