TriggerBypassing

Trigger bypassing

To study trigger efficiencies it is possible to ignore the L1 and L2 trigger algorithms for a configurable proportion of events. Every event will bypass L1 and L2 with an adjustable probability L1BypassProbability. If an event is bypassing L1 it will get the L1 trigger type word defined by the option L1BypassTriggerWord. Events reaching L2 that did not bypass L1 will bypass L2 with the probability defined by the option L2BypassProbability and get the L2 trigger type word defined by L2BypassTriggerWord if they did so. Events that already bypassed L1 will also get the L2 trigger type word defined by L2BypassTriggerWord.

All parameters can be defined in the trigger configuration file /etc/na62-trigger.conf
