pT cut off studies

Fig.1 Fitting Iron data with : p0*exp(-pT2/p1)+ p(p0,p1,p2)*(1/(pT2)^(p2)) and p3 - a 'stiching parameter'
Black solid line - fit region; Green line - extension of fit in a black region; Yellow = exp part of fit


Fig.2 Deuterium. Left plot -Fitting with above expression for Iron. Right - fit with Exp up to 1 GeV2.


Fig.3 Deauterium(left) and Iron(right) targets from reconstructed MC.
Red - all rec 2photon pairs; Black - rec with (gen,rec)photon matching.
