4  Features can be retrieved through the “TriggerNavigation” using the TrigDecisionTool  Features are created by FEX algorithms. They appear in StoreGate in containers according to FEX name. A FEX also creates a “TriggerElement” (TE)  A TE is used as handle to the feature  A TE has a pass/fail state set by the HYPO corresponding to the FEX  So the navigation can give you the TE’s for all the FEX that run in a chain  Or just those that passed the last step in the chain  From there you get the features (type templated)  This is the correct way to retrieve the features for each RoI  Features can be retrieved through the “TriggerNavigation” using the TrigDecisionTool  Features are created by FEX algorithms.

7  Analysis based on single trigger chain or an ‘OR’ of a few chains  Chain definition – algorithms, cuts, multiplicities – do not change during a run, but can change between runs  Important for analysis on DPD, where multiple runs are merged  Prescales at LVL1 or at HLT can change between luminosity blocks  A negative prescale means that this trigger is off. This is important for calculating the integrated luminosity  Analysis based on single trigger chain or an ‘OR’ of a few chains  Chain definition – algorithms, cuts, multiplicities – do not change during a run, but can change between runs  Important for analysis on DPD, where multiple runs are merged  Prescales at LVL1 or at HLT can change between luminosity blocks  A negative prescale means that this trigger is off.
