AUX laser that is to be injected in HAM5 from SRM HR side for later alignment work was prepared in the lab. It's smaller than the real IFO beam but it will do OK. In the 1st attachment, left is the SRM transmission path, green is measured in the lab, red is a fit, blue is the IFO. Assumption was made that the distance from SRM HR to the collimator telescope of the laser is 1.5m, it turns out that it's probably more like 2m or so, but it's not a huge deal. Right is the SRM reflection going to SR2.

We placed the telescope, a metal mirror and a BS roughly in place in HAM5 but didn't adjust it because SOP was not fully signed in time. We left these components inside and closed the chamber for today.
