Peter or anyone who can use this,
I woke up (yes just now) with the following idea. We do have an info on
individual nc tube in the eep ntuple. Say you want to look at neutron
bar 0:
for nnl==0 you have
tnl = (tnl0l + tnl0r)/2 and
pnl = (tnl0l-tnl0r) ( or other way around, one needs to check)
hence it you want to plot tnl0l you can plot (2*tnl+pnl)/2 for nnl==0.
This way you can make cuts on tofs for the eep events.
Cheers, Vitaliy
