Today, Travis and I used the red visible AUX laser to final align the ITMY elliptical baffle and the BS AR and HR baffles. (Note, we had already done the BS baffles and the ITMX but wanted to check and document. Note, the front back, and center targets of the elliptical baffle boxes do not all exactly line up, but the tolerance is 7mm so we are center to better than that on all of them.
Also, note, the BS baffles do not look very centered on the mounting to the BS structure, but the beam is centered thru the baffle, so can't do much about that.
Pictures are attached.
