[Gate-users] z-source in root file

[Ismet Isnaini]

Hi, all GATE gurus.. 

I would like to
ask you a clarification about one matter.Here i attached 2 files ; first file is the result of z-position in the root file, the second one is the axial-sensitivity for the same scanner. I don’t understand what is the y-axis
represent in the root file ? Number of count ?
Because if we see
the second picture which is derived from the root file,
the maximum number of count is only around 800 while the number of total count is similar to the number of
entries written in this z-source root file i.e 291063 entries). Note that scatter and random count for the second file is almost zero.
 
So, what does the
y-axis of this root file represent ?
 
Thanks in advance
for your help
 
Regards
