Data formats in HLTrigger

Complete: 5

Event content definition

Filters are available to select/skim events based on L1 trigger bits (class HLTLevel1Seed) or on HLT trigger bits (class HLTHighLevel) - the user just has to configure the module instance by supplying the list of L1 trigger names or HLT trigger names s/he is interested in.
A single filter (see TriggerResultsFilter) also exists, able to skim on both L1 and HLT results.

InputTag/Module (Instance name) Containers Description
HLT trigger collections (in RECO and AOD)
TriggerResults edm::TriggerResults One EDproduct per HLT table: the HLT decision - global, and for each HLT trigger path: Ready (ie, Not Run), Pass (Accept), Fail (Reject), Error (Exception)
hltTriggerSummaryAOD trigger::TriggerEvent One EDproduct per HLT table - contains L3 collections and L3 filter decisions
hltTriggerSummaryRAW trigger::TriggerEventWithRefs One EDproduct for each HLT path in the HLT table - contains Ref links pointing to the original HLT collections and records filter decisions
HLT filter module label trigger::TriggerFilterObjectWithRefs one of these by every HLT filter module - transient - used to provide information put into persistent TriggerEvent or TriggerEventWithRefs
hltTimer edm::EventTime containing a vector of edm::ModuleTime Simple class for Rate/CPU/Wall time benchmarking of algorithms - generic, not HLT specific
