Thermometer Computer Vision

I designed an instrument which can play polyphonically without adhering to Equal Temperament. If you don't know what that means, or would like to see other instruments I have devised but not built, click here.
A project I did as an undergraduate researcher at MIT. I created "acceptance maps," which mapped areas of the CLAS detector (at Jefferson Lab in Newport News VA) which had higher or lower detection efficiencies, which were used afterwards to weight data for analysis.
Then, I analyzed electron scattering data in order to test the accuracy of the reconstruction of the beam energy. With a deuterium target, the nucleus is only two bodies, so if one is detected, we assume the other has equal and opposite momentum, and our equation for the initial electron energy is exact.
The above plot shows an estimate of background events making the energy reconstruction histogram less precise. I was able to estimate these background events by using the acceptance maps I made.
