Reduicng rates for certain xgamma lines
Rate reductions for lines involving a Lambda/Kstp and a converted photon. The LambdaDD + gammaDD in particular is extremely challenging as the pointing is very imprecise, necessitating the definition of new "tight" lambdas and converted photons.
- Lb->LGamma: Tighter MTDOCACHI2, VCHI2, sum pT
- Lambda: Tighter mass windows
- New tight Lambda (for LGamma only): Daughter IPCHI2>10, DOCACHI2<10
- New tight converted photon (for LGamma only): pT>2GeV
- Kstp->KSpip: Tighter pT and sum pT
BW running over all RD turbo lines decreases by 24MB/s; rate by 600Hz
