Links that go no place mean that no one has provided the trigger description. The priority of the labelling of an event in the case that more than one hardware trigger is satisfied is listed in the PRUDE KPRID prioirty table as KPRID = 10 * GM.

Descriptions of the different MLUs are also available:

  • CMLU:Charged MLU.
  • PMLU:Phi MLU.
  • NMLU:Neutral MLU.
