However this variable ignores correlations between different event types
for the same event. Hence you only know which event type came first and
not what other event types were present at the TS.
Also the raw coincidence time variable is now gone: DBB.t3, since ROC 10 is
not read out. But thankfully there is a copy on the left arm that I will
