BSC06 ETMy Yaw Alignment
IAS: J. Oberling
SEI: H. Radkins, J. Warner, G. Grabeel, E. Allwine

While Hugh & Co. were adjusting the ISI level we also went ahead an aligned the ETMy yaw.  It started at 1.2 mrad CCW (top-down view) and we left it at 30 µrad CCW; spec for HEPI yaw adjustment is 0 ± 160 µrad.  ETMy pitch is currently at 300 µrad down (desired pitch is 639 µrad down) so some adjustment there is necessary upon Travis's return next week.

Jason and I concluded the work with some level shots on the ISI Optical Table.  We took three shots on the optical table and see a range of 0.4mm with the highest point being right at design elevation of 1661.7mm above chamber zero.  This was shot with the HEPI floating and the ISI unlocked.
