Last Fri (12/1), I went into BSC1/2/3 to take a few photos. Betsy requested a few line of sight photos of (ITMx to PR2) & (ITMx to SR3)--these shots are to highlight/show the baffling involved in these paths (so we have baffles around the BS and also on the BS Suspension structures).
I took 150+ photos, but unfortunately I don't have a place to upload them (resourcespace has had issues for me for the last year or two). Photos will be on my computer. Am also attaching some highlights (their names roughly say what is in the photo---it's hard to tell what's in the pictures, but I am hoping I've labeled them correctly).
Note, everywhere Corey states ITMx to PR2, he means PR3...
Recall, these baffles were aligned to the beam and not the BS optic - the error between the two is only ~2mm, per alog 39344.
