19 | // Implementation of Class AliPhysicsSelection | |
528640ed | 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 | // | |
a2ce3799 | 25 | // Create the object: |
528640ed | 26 | // fPhysicsSelection = new AliPhysicsSelection; |
a2ce3799 | 27 | // |
28 | // For MC data, call | |
29 | // fPhysicsSelection->SetAnalyzeMC() | |
528640ed | 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 | // | |
73cc8654 | 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 | // | |
85c71ba7 | 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 | // | |
decf6fd4 | 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 | // | |
