[gate-users] Transportation process in gateHits.dat

[Bing Bai]

Hi,

When checking the gateHits.dat generated from my PET scanner simulation, I 
found a small portion of the hits are labelled as "Transportation" and the 
energy deposited is not zero. Are these so called "special hit" in user's 
manual Chap 8.1, when a particle moves from one volume to another? 
If so why the energy deposit is non-zero? (according to the user manual it 
should deposit zero energy.)
And I found some hits in the same file with zero energy deposit, but are 
labelled as other process such as Compton.

Thanks,
Bing
