Having generated either ASCII or ROOT output, count those events (coincidences) having the same eventID, different volumeID as well as registered within a pre-determined time-window (since the Gate tags a time on each event, i.e., the timeID). But this is just an idea, and thereby needs to verify.</div><div id="yui_3_16_0_1_1416114179067_18700" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1416114179067_18700" dir="ltr"><span id="yui_3_16_0_1_1416114179067_18757">Hope this help!
