It seems to be related to the energy blurring. When I change the resolution to 0, the bin bar of 511Kv stands out again in the case of Ga68.
# energy blurring
eb = sim.add_actor("DigitizerBlurringActor", "Singles3")
eb.output = f"pet1s.root"
eb.input_digi_collection = "Singles2"
eb.blur_attribute = "TotalEnergyDeposit"
eb.blur_method = "InverseSquare"
eb.blur_resolution = 0 #0.112
eb.blur_reference_value = 511 * keV
Hello,
When I ran the pet simulation, I found a strange thing. When I use F18 as source energy, the distribution of edep in root file is like this:
However, when I use Ga68 as source energy, the distribution of edep in root file is like this, the peak energy is not in 511Kv.

I would like to ask if is it normal. Thank you.
The code I use is as below:
