Hi Gaters,<br>
<br>
I am trying to understand results output by the dose actor, which I enabled with the following lines:<br>
<br>
/gate/actor/addActor DoseActor             dose5<br>
        /gate/actor/dose5/save                   results/dose_2021May11_171652_5.root<br>
        /gate/actor/dose5/attachTo               box5<br>
        /gate/actor/dose5/stepHitType            random<br>
        /gate/actor/dose5/setResolution          1 10 1<br>
        /gate/actor/dose5/enableDose             true<br>
        /gate/actor/dose5/enableUncertaintyDose  true<br>
        /gate/actor/dose5/enableNumberOfHits     true<br>
<br>
The source is a pencil beam of protons of 100 MeV. I simulated 10000 events.<br>
<br>
Here is the histogram I got:<br>
<br>
<br>
My question is why is the error so large? How is it calculated?<br>
<br>
Cheers,<br>
<br>
Dmitry<br>
