Dear Giuseppe and Francesco,
Thanks for your comments.
I have another question about the ATRACK variable which represents the age of particle. If i try to
obtain the absolute time distribution of generated photons into the detector, the time when the photon
is generated is needed and how should i get this "time" ?
Best regards
Bo Yang
