Detailed Description

Base class for analyses using EMCAL triggers.

Author: Markus Fasel marku.nosp@m.s.fa.nosp@m.sel@c.nosp@m.ern..nosp@m.ch, Oak Ridge National Laboratory

Date: Oct. 6, 2016

Base class for analyses using EMCAL-triggered events. This class provides several extra funcitonalities shared among different tasks

Handling of downscale weights for downscaled triggers
Handling of online trigger cleanup (requirement of recalc patch above threshold to select event)
Trigger classification, also for exclusive classes (classes not containing lower classes)
Histogram management via THistManager

This class is abstract. Users have to implement at least the following two functions

void CreateUserHistos(); // Instanciation of histograms within the histogram manager

void CreateUserObjects(); // Handling of other objects the user might need in the analysis

The task runs a common (default) event selection. Users can implement additional event selection

Bool_t IsUserEventSelected();

This function is running only in case the common event selection is passed.

Two functions implement monitoring

void UserFillHistosBeforeEventSelection(); // Filling distribuions before event selection

void UserFillHistosAfterEventSelection(); // Filling distribuions after event selection

Otherwise the class uses functionality of the AliAnalysisTaskEmcal. This includes the main function

Bool_t Run();

which contains the main event loop.

Second approach: We assume masked fastors are already handled in the trigger maker. In this case we treat masked fastors similarly to online masked fastors and apply online cuts on the recalc ADC value. Implemented for the moment only for L1 triggers.

Returns: True if the event has at least 1 recalc patch above threshold
