[Gate-users] Detector response and FFDA

[Simon Rit]

Hi,
The detector response is a piecewise linear 1D function of the energy. The
fist column is the energy of the incident photon in MeV in the default
Geant4 energy (MeV if you haven't modified it). The second column is the
corresponding measured signal in a unit that you chose.
