I went in to have a quick look at the HWSX table and hoping it would be a quick fix to get the SLED beam centered without taking the Hartmann plate off. However, I couldn't get the streamed images to look any better as I move the periscope mirrors so I took the Hartmann plate off to see what the beam looks like. I've attached a picture. The earthquake stops are there so the beam *should* be  roughly centered. Is this a scaling problem? Or do we have dead pixels somewhere?

I put the Hartmann plate back on although the streamed image seems useless...
