Vitaly,
it must be you, or your cuts, or at least it's not me..
See attach Q2 spectrum with one cut only "qwl==-1". By chance the scales
is the same (x100..). My plot does not fall off as fast as yours.
Situation does not changes with ep QE cut (pm_eep_cut)
Actaully, also chi's data match reasoanble well in that Q2 area.
Are you sure you don't have e- momentum cuts or else ?
how do you filter data ?
