[b1_ana] Evening Update

[Long, Elena]

Good evening,

I've realized that in the plots I've been showing thus far, I've included an arbitrary cut of plus/minus 0.1 for each x point shown on Azz. Removing this cut increases our rate by about a factor of two. I've also added, in grey, the total acceptance of the spectrometer and colored in blue and red, the physics acceptance (W>2). Patricia noted that we could also park the HMS at a high x point for the entire run period, so I've added that point as well.

Please note that on Azz and b1d, the central x values for the two highest points will shift to the left. I'm still working on what the central values for those points actually are, weighted to the acceptance cuts, but you can get a sense of it from the kinematics plots (especially theta_e').

Take care,
Ellie
