Azz with Color-Coded Plots

---

I took the edited the output of Azz plots so that they have their own, dedicated grace files. I then replaced the b1 plot with the dilution factor and shaded the kinematics plots by the total cross-section (N+He+2H), where darker = larger cross-section and lighter = smaller cross-section. The cross-sections each have 20 shading bins, with the cross section in that section being linearly scaled to fit from 1-20. This means that it's not the same scale across spectrometers, or from cuts to background, just to keep in mind. I included it to get a sense of where our data is coming from.

I also changed the "Physics Rate" to mean the rate from 2H within the kinematics cuts. Previously, it was the total rate (14N+4He+2H) within the cuts.

No Cuts

If we don't make any cuts on the kinematics, we can get a sense for the cross-section everywhere:

0.75<x<1.85 Cut

If we then add the x cut, the thrown-out events, still in grey, are now also shaded:

0.75<x<1.85 and Q^2>1 Cuts

And adding a Q2>1 cut:

HMS_min=12.2 degrees

If it turns out that the HMS is restricted from the target to a minimum angle of 12.2 degrees, then we can expect the following:
