Dear all,
I am trying to simulate a CT scanner. For source definition, I need to use arbitrary point-wise spectrum "Arb" as following command:
/gate/source/xraygun/gps/histpoint energy (MeV)     ????
Please guide me what is the second column in the command? Photon fluence (photon/mm2.s)? or photon flux (photon/s)? or number of photons in source?
Best Regards,Masoud
