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 | // | |
25 | // Create the object and initialize it with the correct run number: | |
26 | // fPhysicsSelection = new AliPhysicsSelection; | |
27 | // fPhysicsSelection->Initialize(104160); | |
28 | // | |
29 | // To check if an event is a collision candidate, use: | |
30 | // fPhysicsSelection->IsCollisionCandidate(fESD) | |
31 | // | |
32 | // After processing save the resulting histograms to a file with (a folder physics_selection | |
33 | // will be created that contains the histograms): | |
34 | // fPhysicsSelection->SaveHistograms("physics_selection") | |
35 | // | |
36 | // To print statistics after processing use: | |
37 | // fPhysicsSelection->Print(); | |
38 | // | |
