Add DeltaEtaDeltaPhiMinvPtCent histograms with coarse binning as THnF for same event and mixed event to the mesonQA (roughly 3 MB per histogram). These histograms should allow to analyze the side band and peak invairant mass regions for DeltaEta and DeltaPhi correlations to study the impact of:

  • flow: cos(n * DeltaPhi) over all DeltaEta
  • resonance decays: near side peak around (DeltaEta,DeltaPhi) = (0,0), narrow in DeltaEta
  • back to back jets: away side excess around DeltaPhi = pi

Removes old and unused configurable maxEnergyAsymmetry
