So, once again, the cross section model for 3He goes to zero before the cross section does (about x=2.95), which means that the last couple of bins are troublesome. In the code, I "fixed" this by going back as many bins as was necessary until I found a non-zero cross section and used the last two non-zero points in the model to get a slope and use that to get a weight for Y_MC. However, I noticed that I still had a ton of negative weights (which I threw away). I assumed I had a typo, but no, this method gave slopes that were too steep and when extrapolated to x~A, it would cross into the negative.

So, this is what we're trying now - stop trying to bin-center in x altogether, since my bins are so small that the average x IS the center x (Nadia, you're SO awesome, you don't hear that enough). Continue to bin center in theta, but if the cross section is missing, go from last known cross section to 0 at x~3. We get the plot below - recover a couple of points, and don't break the others (because apparently, the bin centering wasn't doing much anyway).
