I am still working on the energy calibration and the resolution, response, and efficiency plots for neutron samples

1. For the resolution, response, and efficiency plots, Kiley raised a question about a maxima in the resolution around 25 GeV. I have highlited this in my slides. We think that this may be due to some non-gaussian behavior in the fits for this region, so I have also attached all of the subfits as a PDF.
2. In terms of the energy calibration, I think that I have a bug in my code that I haven't found yet because the profile along theta has much larger errors in the 0-50 GeV batch compared to the other two sample batches. Also, this batch has a 5-6x larger correction factor.
   1. It would make sense to me for the sim-to-digi conversion to follow the response curves that I already generated (in my slides). The 0-50 GeV response is roughly -.15 while the 250-1000 GeV response is around -0.025. This is a 6x difference which is the same as the difference I see in the sim-to-digi conversion. Could this possibly explain the differences that I'm seeing in my conversion profile? Or am I thinking about this incorrectly.
3. With the new computing setup, I am planning to run comparisons with the 3 TeV data as well.
