  • For small q_inv a correlated contribution arises which is cause by pairings of a photon where the electron leg produces Bremsstrahlung and this photon converts again and is reconstructed. This is why I want to try out whether a template developed in peripheral collisions would allow me to describe this contribution and this commits adds the necessary histograms for that in the builder as well as the photonhbt task. Additional Bremsstrahlungs response matrices are also filled in photon HBT now to correct for eventual pT smearing.
  • Additionally I wanted to add more granular centrality bins in the new mixing method.
