Detailed Description

A set of histograms for resolution. The fill method requires the two selected muons, their charges and the reconstructed and generated masses. It evaluates the resolution on the mass vs: Pt of the pair DeltaEta of the pair DeltaPhi of the pair pt, eta and phi of the plus and minus muon separately
