Contains some example configurations of the FEI
Mostly you want to use get_default_channels,
which can return the configuration for common use-cases
- Hadronic tagging (hadronic = True)
- Semileptonic tagging (semileptonic = True)
- B+/B- (chargedB = True)
- B0/anti-B0 (neutralB = True)
- running on Belle 1 MC/data (convertedFromBelle = True)
- running a specific FEI which is optimized for a signal selection and uses ROEs (specific = True)
- run without semileptonic D channels (removeSLD = True )
- B mesons with a strange quark in Y(5S) runs (strangeB = True)
Another interesting configuration is given by get_fr_channels,
which will return a configuration which is equivalent to the original Full Reconstruction algorithm used by Belle
