Detailed Description

Unit test class for charged particle distributions (MC case)

As generator of reference distributions this task is written as "must work", meaning as simple as possible and as independent as possible. Using only well-tested components. Objects responsible for further problems, i.e. the usage of THnSparse due to memory problems in several places, are forbidden.

protected

Apply additional cut requiring at least one offline patch above a given energy (not fake ADC!) Attention: This task groups into single shower triggers (L0, EG1, EG2) and jet triggers (EJ1 and EJ2). Per convention the low threshold patch is selected. No energy cut should be applied in the trigger maker

Parameters

trgcls	Trigger class for which to apply additional offline patch selection
triggerpatches	Array of trigger patches

Returns: True if at least on patch above threshold is found or no cut is applied
