[Gate-users] Meaning of attachTo in phase space source

[David Sarrut]

Hello Stathis,

- to attach the phase space (with the attachTo command) to a volume V means
that particles information will be stored in the phase space only when they
reach the volume V

- in your question you may refer to the "useVolumeFrame" flag ? If the flag
is off (default) the particle coordinates are expressed in Gate world
coordinate system. I the flag is on, the particle coordinates are expressed
in the volume V coordinate system. It means that when using the phase space
as a source, if you change the position of the volume V, particle will also
be moved. This is not the case if the flag is off.
