Analysis
After my first attempt at reconstructing the theta_abs distribution gave mediocre results, I decided to try again, but this time without integrating over experimental observables throught analysis, except for at the final step. To illustrate what I mean, see the histogram below:
The benefit of conducting the analysis in this 3D space, is that the photo-neutrons correlated with the beam can be normalized to uncorrelated Cf252 neutrons detected in the same detector with similar positions and energies.
