So, this is the cold startup where we are aiming at sending beam to 3R in order to be able to do ARC2/ARC1 M56, poathlength ,etc.. Hence, no match is performed yet (other than INJ->NL). You can see on these plots that the beam is not optimally match.

This will be addressed when we go through the ORFP.

Noted 2A SLM was a vertical stripe so we decided to check the viewers. Everything seems relatively reasonable apart from not seeing beam on ITV2L14 (perhaps it's through the hole?) and ITV2L10 being out of focus. The last figure is the SLM that spurred this check.
