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
22//
23// Usage:
24//
25// Create the object:
26// fPhysicsSelection = new AliPhysicsSelection;
27//
28// For MC data, call
29// fPhysicsSelection->SetAnalyzeMC()
30//
31// To check if an event is a collision candidate, use:
32// fPhysicsSelection->IsCollisionCandidate(fESD)
33//
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")
37//
38// To print statistics after processing use:
39// fPhysicsSelection->Print();
40//
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,
44// use:
45// fPhysicsSelection->SetUseBXNumbers(0);
46//
47//
48// If you are analizing muons and you want to keep the muon triggers
49// besides the CINT1B you can set:
50// fPhysicsSelection->SetUseMuonTriggers();
51//
52//
53// To compute the Background automatically using the control triggers
54// use:
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.
63//
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").
77//
78//
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()
81// Example:
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
92// to be present:
93// AddBGTriggerClass("+CSMBA-ABCE-NOPF-ALL -CSMBB-ABCE-NOPF-ALL");
94//
95// The class also supports the triggers used in heavy ion runs
