Greetings again,

I use PLUTO for simulating eta dalitz decays produced via photoproduction on a liquid hydrogen target (gamma p -> p eta [e+e-gamma]). I ensure that I use a beam profile of a 1/E(gamma) in the simulation, however the reconstructed parameters do not match the data.

So what I would like to do is use the data itself as the initial parameters and have PLUTO decay the eta via dalitz decay, ie event by event use the parameters:
Photon Beam Energy (0, 0, E, E)
Proton "myproton = P3M(px,py,pz,mass);"
Eta "myEta = P3M(etapx,etapy,etapz,etamass);"
then use
PReaction my_reaction("Beam_Energy","g","p","myproton myeta [dilepton [e+ e-] g]","eta_data_simulate",1,0,0,0);

Is it possible, since these variables are from data, to only have the eta dalitz physics operational when running PLUTO?
