Earlier last week when we were using the red eye safe alignment laser to align the elliptical baffles in BSC2, I also checked and tweaked the HWS paths on HAM4.  Reasons for doing this were that

1) I moved the 4" HWSX steering mirror a few weeks ago in order to install the scraper baffle and slide the SRM cage back 5mm

2) We bumped a 2" steering mirror on the HWSY path (the one most central to the table)

Indeed, we found both paths slightly misaligned - both beams made it through the last lens out the VPs, but were off center.  I tweaked only the mirrors above, knowing that those were the ones with issues.

I verified that the beam is well centered into the HWSX scraper baffle which was upgraded a few weeks ago.  I also did a quick check that the beam is ~well centered going through the HWSY scraper baffle.

I made Aidan aware that I was doing this.
