15 | // AliAnalysisTaskCheckPerformanceCascadePbPb class | |
16 | // This task is for a performance study of cascade identification in PbPb. | |
39b18694 | 17 | // It works with MC info and ESD/AOD. |
f9a6cab5 | 18 | // Origin : AliAnalysisTaskCheckPerformanceCascade class by A. Maire Nov2010, antonin.maire@ires.in2p3.fr |
19 | // Modified for PbPb analysis: M. Nicassio Feb2011, maria.nicassio@ba.infn.it: | |
39b18694 | 20 | // - physics selection moved to the run.C macro |
21 | // - added centrality selection and possibility to select events in nTracks ranges | |
f9a6cab5 | 22 | // - added new histograms |
23 | // - modified binning of some histograms and containers | |
24 | // - flag to enable CF container usage | |
39b18694 | 25 | // - check in the destructor for CAF usage |
f9a6cab5 | 26 | // - flag for acceptance cut in the MC part |
27 | // - in the MC particle selection IsPhysicalPrimary added and number of particles taken as appropriate for HIJING | |
39b18694 | 28 | // (however for cascades one gets the same if runs on Nprimaries in the stack and does not check IsPhysicalPrimary) |
29 | // - automatic settings for PID | |
30 | // - selection of injected cascades and HIJING cascades (kind of "bug" in method IsFromBGEvent()) | |
31 | // - added proper time histograms for cascades and lambdas | |
32 | // - cos of PA V0 wrt Xi vertex and not primary vertex | |
33 | // - distance xi-V0 added in the container | |
34 | // - AOD analysis developed (January 2012) | |
f27a407b | 35 | // - cut on TPC clusters as a parameter |
6fd25d0b | 36 | // - cut on min pt of daughter tracks added (parameter+control histos) |
37 | // - cut on pseudorapidity for daughter tracks as a parameter (+control histos for Xi-) | |
