19 // Implementation of Class AliPhysicsSelection
20 // This class selects collision candidates from data runs, applying selection cuts on triggers
21 // and background rejection based on the content of the ESD
26 // fPhysicsSelection = new AliPhysicsSelection;
29 // fPhysicsSelection->SetAnalyzeMC()
31 // To check if an event is a collision candidate, use:
32 // fPhysicsSelection->IsCollisionCandidate(fESD)
34 // After processing save the resulting histograms to a file with (a folder physics_selection
35 // will be created that contains the histograms):
36 // fPhysicsSelection->SaveHistograms("physics_selection")
38 // To print statistics after processing use:
39 // fPhysicsSelection->Print();
41 // The BX ids corresponding to real bunches crossings p2 are
42 // automatically selected. You cannot process runs with different
43 // filling schemes if this option is set. If you want to disable this,
45 // fPhysicsSelection->SetUseBXNumbers(0);
48 // If you are analizing muons and you want to keep the muon triggers
49 // besides the CINT1B you can set:
50 // fPhysicsSelection->SetUseMuonTriggers();
53 // To compute the Background automatically using the control triggers
55 // fPhysicsSelection->SetComputeBG();
56 // this will show the value of the Beam Gas, accidentals and good
57 // events as additional rows in the statistic tables, but it will NOT
58 // subtract the background automatically.
59 // This option will only work for runs taken with the CINT1
60 // suite. This options enables automatically also the usage of BX
61 // numbers. You can only process one run at a time if you require this
62 // options, because it uses the bunch intensity estimated run by run.
64 // The BG will usually be more important in the so-called "bin 0": the
65 // class can also compute the statistics table for events in this
66 // bin. Since the definition of bin 0 may in general change from
67 // analysis to analysis, the user needs to provide a callback
68 // implementing the definition of bin zero. The callback should be
69 // implemented as a method in the analysis task and should override
70 // the IsEventInBinZero method of AliAnalysisTaskSE, and should thus
71 // have the the following prototype:
72 // Bool_t IsEventInBinZero();
73 // It should return true if the event is in the bin 0 and it is set by
74 // passing to the physics selection the NAME of the task where the
75 // callback is implemented:
76 // fPhysicsSelection->SetBin0Callback("MyTask").
79 // Usually the class selects the trigger scheme by itself depending on the run number.
80 // Nevertheless, you can do that manually by calling AddCollisionTriggerClass() and AddBGTriggerClass()
82 // To define the class CINT1B-ABCE-NOPF-ALL as collision trigger (those will be accepted as
83 // collision candidates when they pass the selection):
84 // AddCollisionTriggerClass("+CINT1B-ABCE-NOPF-ALL #769 #3119");
85 // To select on bunch crossing IDs in addition, use:
86 // AddCollisionTriggerClass("+CINT1B-ABCE-NOPF-ALL #769 #3119");
87 // To define the class CINT1A-ABCE-NOPF-ALL as a background trigger (those will only be counted
88 // for the control histograms):
89 // AddBGTriggerClass("+CINT1A-ABCE-NOPF-ALL");
90 // You can also specify more than one trigger class in a string or you can require that some are *not*
91 // present. The following line would require CSMBA-ABCE-NOPF-ALL, but CSMBB-ABCE-NOPF-ALL is not allowed
93 // AddBGTriggerClass("+CSMBA-ABCE-NOPF-ALL -CSMBB-ABCE-NOPF-ALL");
95 // The class also supports the triggers used in heavy ion runs
