In this section I will investigate the behavior of the central peak on the GenPart.z - Event.z histograms for different annular regions along an extended cylindrical target. While sifting through histograms that had been made, I noticed that there was a shift in the mean value as Z extends away from zero. Below is an example.
Here it can be seen that near zero, the mean value is 0.08 cm, while in the histogram that places the cut further away from zero has a mean value of -1.693 cm. I will make histograms from a ROOT file generated by reconstructing a GEMC 2.5 evio file using Coat-Java 2.4.
