Question Meaning of /gps/pos/sigmax 

Forum: Geometry
Date: 27 Jan, 2015
From: Andrea Conti <Andrea Conti>

If I have well understood, setting a certain geometrical volume as source using the general particle source makes Geant4 produce particles in that volume with a CONSTANT probability density. Therefore the standard deviation should be the constant probability density's standard deviation. But according to the guide for application developers one can set f.e. the x-standard-deviation to a certain wished value using /gps/pos/sigmax. How is it possible ? Can anybody explain the real meaning of the commands /gps/pos/sigmax, /gps/pos/sigmay etc. ? And why is the default standard deviation = 0 (according to the guide)?
