Mitchell and I got the last corner of HEPI Actuaots attached. IAS was at the ready and noted a need to Yaw CW ~140urads. The SEI Dial Indicators suggested ~70 shift CCW from last IAS position. I thought they be better than that but at least they're in the same direction. I turned the HEPI DSCW Springs to compensate (1/4 Turn on every spring.) This put us about 20urads to go. We left it there and checked again after lunch and it looked maybe slightly better, a few urads, and this jived with some slight changes on the DIs.
The last time SEI did an elevation survey combined with the changes on the DIs since then suggest Elevation & Level of the optical table are 0.2mm high of nominal with just 0.2mm of level runout--at spec of 100urads.
With that I zero'd the HEPI Actuator IPS (Inductive Position Sensors) to less that 50 cts, most much less but it is mainly luck at that point. At the raw IPS there are 655cts/0.001" so comfortably under 0.0001". I also checked the gaps between the Actuator Plate and the Bellows Shields which form a range of motion limit and sensor protection mechanism, and these seemed mostly centered well enough. Range of motion and linearity tests will confirm if we are good there.
I'm sure Jason will put in an IAS log, otherwise, SEI/HEPI is good.

While Hugh and Mitchell were working on HEPI during this morning, Margot, Kate, and I did more cleaning inside of WBSC10. We wiped the ACB, viewports, and flooring again. We also wiped the barrel of the ERM more. We removed the ACB target and the ETMy-HR First Contact in order for IAS to continue alignment of the TMS through both the ACB and ETMy.
The floor in the tube nearest the purge port seems to have the most amount of particulate accumulation, although it hasn't had any cleaning attention like the BSC chamber has. We intend to take some samples and then clean it up.
