J/psi muons
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.
