[Gate-users] About the Judgement of true coincidence, random coincidence and scattered coincidence

[Arno_gmail]

Hello everyone:
I am confused with extracting the true  coincidences, random coincidences and scattered coincidence from root file, and do not know whether it is right to do as follows.




		if ( eventID1 != eventID2 )
		{
			Nbr_Coinc_Random++;
		}
		if(eventID1 == eventID2&&(comptonPhantom1 != 0 || comptonPhantom2 != 0))
		{
			Nbr_Coinc_Scanners++;
		}
		if ( eventID1 == eventID2 && comptonPhantom1 == 0 && comptonPhantom2 == 0 )
		{
			Nbr_Coinc_Trues++;
		}



By the way, what is the definition of "prompt  coincidences". Thanks a lot! Best wishes!
