[Gate-users] Coincidence timing window

Dear Gaters,

I am simulating a PET scanner, but I am really confused about the
coincidence timing window. The manifacturers provide it as 2*tau. If I set
the window value as (tau =) 6 ns, and when I look at the histogram of the
time1-time2 of the coincidences, I see that I have coincident events
between t-tau and t+tau. That means the coincidence resolution is about 6
ns FWHM. So in my case, do we define my coincidence window as 2*6 ns? How
should I set it in order to match the value of the manifacturer??

Thank you very much in advance,

All the best,
