used J/psi sample to look at muon eta coverage and mass resolution in different eta regions


Muon eta as function of # CFT hits. cutoff for any # CFT hits comes from the muon trigger.



Profile of #CFT and SMT hits as function of eta.



this shows that nseg<3 muons do not have larger eta coverage wrt nseg=3 muons.



J/psi mass peak for |eta|<0.5. Sigma of the fit is 69 MeV.



J/psi mass peak for |eta|>1.5. Sigma of the fit is 91 MeV.
