There was a lingering problem with the clustering program that was taken care of today (after much searching and debugging). I had moved the actual clustering chunk of the code into the jet loop to run it over multiple jets, which meant I didn't know how many particles were in each jet or what their energies were. The error occurred when the minimum particle energy was greater than the cluster threshold energy, thereby causing the program to loop indefinitely (or until an array was overloaded). 

    With that resolved, I began running through individual jets in hopes of adding their histograms to get a meaningful peak.
