[Gate-users] TOF problem

[Йордан Маджунков]

Hi,
t1 and t2 are the time of arrival of photon1 and photon2. Keep in mind that 1 and 2 are "randomly" assigned in each decay. Therefore it's more than normal to get the same distribution even if on average your photons don't travel same time before they reach the detector.
