[Gate-users] Detector response and FFDA

[Shiras Abdurahman]

Hi,

Thank you very much for the answers. Earlier, I was using the detector
response present in the gate examples CT folder (vGATE 7.2). It looks like
this
0 1
1 0
Does this mean an ideal energy integrating detector with equal weighting
for all the energy bins?
