BPHY13, 23 and 25 update
Updated BPHY13, BPHY23 and BPHY25. For BPHY13, made 4-muon single-vertex fit with charmonium mass constraints (instead of replying on charmonium revertex). For BPHY23, added the multi-track single-vertex fitter and corresponding changes in python. For BPHY25, removed Ks and added 3-body decays like B- -> J/psi Lambda pbar, and corresponding changes in python. Development of BPHY13, BPHY23 and BPHY25 can be found in the following JIRAs: https://its.cern.ch/jira/browse/ATLBPHYS-34
