Hi Tahereh,
That could be because you are counting scattered randoms as both scattered and randoms, if I am not mistaken.

Subject: [Gate-users] Number of coincidences

Hi,

Does anyone know why the total number of coincidences is less than the sum of the trues, randoms and scatters?


if ( eventID1 != eventID2 ) Nbr_Coinc_Random++;

if ( eventID1 == eventID2 && comptonPhantom1 == 0 && comptonPhantom2 == 0 ) Nbr_Coinc_Trues++;

if ( comptonPhantom1 > 0 || comptonPhantom2 > 0) Nbr_Coinc_Scatter++;

Regards,
Tahereh
