[Gate-users] root output histogram - Ion_decay_time_s

[Marcin Balcerzyk]

Dear Gaters.

Anybody knows which part of Gate produces the histogram  Ion_decay_time_s,
found in the begining of root file (wood?),above Hits, Singles etc.?
BenchmarkPET.C uses it to count the amount of processed decays. There is
generation of this histogram in
http://opengatecollaboration.healthgrid.org/GATEusers/documentation/REFERENC
E_MANUAL/html_v1.1.0/GateToRoot_8cc-source.html lines 00425nn but I cannot
understand where the histogram data come from.

I run into confusion, as I created for my PET system two single chains – one
default Singles, and then using Digigate (digitizer optimization) a second
LESingles from Hits. The amount of processed decays shown by
Ion_decay_time_s is different (factor of three) in input and output root
files, which I find strange, if the Ion_decay_time_s really counts the
processed decays.
