Note that the SR3 oplev sum is ~0, even though it's pretty well aligned. No good.
That would be because the oplev is off. It had to be moved for the grouting last week and in the process was unplugged from its power supply. I haven't had a chance to plug it back in yet.
Due to the grouting, none of the oplevs (except the BS, no grouting was done to it) are good alignment references right now. Once the post-grouting optic alignment work is complete I will realign the optical levers.
