0002
0003
0004 This analysis is intended to make measurements of the Energy-Energy Correlator up to large R_{L} across all of the Calorimeters (starting
0005 with the Outer HCAL)
0006
0007 Intended uses are for a first measurement without tracking and additional studies in the vein of "Jet observables without Jets algorithms"

0076 Currently runs ok on MC data, adding in some fixes to get the real data running better including a more correct jet reco
0077 still need to create the proper dictionary for the ttree to read in the maps correctly
