JB Absolute theta(oldmethod)

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:
