Improvements to J/psi + neutrals lines
- IS_NOT_H>0.2 requirements on photons in line with recommendations in https://indico.cern.ch/event/1517726/contributions/6406274/attachments/3026871/5342702/NeutralPID_bnoc.pdf
- Extended pi0/eta/chic mass windows
- CALO digits and clusters in all lines
- Correct pv_tracks/tagging_particles persistency in all lines
- B-cone isolation in all lines
- Require detached j/psi also in j/psiK*+ and chicK lines (not j/psipi0 or j/psieta)
- Looser selections in j/psietapi line including no deltaM cut
- photon pT:
- pi0: tighten 200->250MeV
- eta: loosen 500->250MeV
- Move jpsietapi line spruce->turbo
- Using
ParticleAdderAssignVtxfor j/psi+neutral combinations with no vertex so that DTF will work
Total rate of all B2CC lines -52 Hz
Total B2CC turbo bandwidth +11MB/s
Sprucing bandwidth change not measured but can only decrease
