Hi all,

I have modified a little bit simplified digitisation of emc to take into account two most relevant parameters: electronic noise and photon statistics.

With UseDigiEffectiveSmearing=1 parameter in emc.par the task PndEmcMakeDigi will smear energy taking into account parameters DetectedPhotonsPerMeV, ExcessNoiseFactor and Incoherent_elec_noise_width_GeV according to:

sigma/E=sqrt((a/sqrt(E))^2+(E_noise/E)),

where a=sqrt(F/N_p.e.),

F - excess noise factor and N_p.e. - number of photoelectrons.

This option can be useful for comparison with prototype data.

Best regards,
Dima
