Detailed Description

Module to analyze pat::Jets in the context of a more complex exercise.

Basic quantities of jets like the transverse momentum, eta and phi as well as the invariant dijet mass are plotted. Basic histograms for a jet energy response plot as a function of the pt of the reference object are filled. As reference matched partons are chosen. Input parameters are:
