Draft: muon chi2
The purpose of this MR is to add another muon discriminator on top of isMuon lhcb/Allen!71. The output of the algorithm is a chi2 distribution on which specific trigger lines could cut on. In particular this could help in the tuning of the current Hlt1LowPtMuon line.
The necessary steps for the validation are:
- Check the throughput of the algorithm and optimise it
- Check the physics performance with a LHCbPR test in Moore
If the above are satisfactory the chi2 output could further be used as an input of catboost, already available in Allen lhcb/Allen!51
