[Gate-users] Noise parameters

[Ashley Devarim]

Hi again,

Thank you very much for your answer,

My concern is that the noise signal is never added to the particle energy signal, they are totally separated  (in GATE) but in real life, the noise is added to the energy signal ?  do you get please what I mean ?


Looking forward to your answer
Best regards

Ashley







> Actually, it depends on what you mean by "coincidence"
> If you're using the coincidence feature of gate (/gate/digitizer/coincidence/...) the module doesn't care about the eventID and so, the noise events will be merged with "physical" events for coincidences (this, because the time flag of the noise events are distributed along the total time of your simulation).
