 I removed the abs(GenPart.x - Event.x)<1 and abs(GenPart.y-Event.y)<1 to have more events in the histograms. Also note that each of these averages were made using a modified fit (slider bar in the FitPanel) to ensure that only the largest peak was involved in the gaussian fit.

 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.

 The first region is the black curve, then regions 2-5 are found by rotating clockwise around the histogram with region 5 being magenta (macro problems renaming stat boxes, will be fixed).
 To investigate further, an xm grace plot will be made of the positive and negative halves of the target to see if there is some sort of trend.
