isn't such a capability in gate! As I found out, one can just select the type (Point, Plane, Volume) and then the shape (rectangular, ellipse, cylinder, ...) of the source. And the gate would sample uniformly over the source. What about if we need a non-uniform
(Gaussian) sampling of particles? Does anybody have a clue on this problem?</span></font><font color="black" face="Helvetica"><span style="font-family:Helvetica;color:black"><o:p></o:p></span></font></p>
