-// AliAnalysisTaskCheckPerformanceCascadePbPb class\r
-// This task is for a performance study of cascade identification in PbPb.\r
-// It works with MC info and ESD/AOD.\r
-// Origin : AliAnalysisTaskCheckPerformanceCascade class by A. Maire Nov2010, antonin.maire@ires.in2p3.fr\r
-// Modified for PbPb analysis: M. Nicassio Feb2011, maria.nicassio@ba.infn.it:\r
-// - physics selection moved to the run.C macro\r
-// - added centrality selection and possibility to select events in nTracks ranges \r
-// - added new histograms \r
-// - modified binning of some histograms and containers \r
-// - flag to enable CF container usage \r
-// - check in the destructor for CAF usage\r
-// - flag for acceptance cut in the MC part\r
-// - in the MC particle selection IsPhysicalPrimary added and number of particles taken as appropriate for HIJING \r
-// (however for cascades one gets the same if runs on Nprimaries in the stack and does not check IsPhysicalPrimary)\r
-// - automatic settings for PID \r
-// - selection of injected cascades and HIJING cascades (kind of "bug" in method IsFromBGEvent())\r
-// - added proper time histograms for cascades and lambdas\r
-// - cos of PA V0 wrt Xi vertex and not primary vertex \r
-// - distance xi-V0 added in the container\r
-// - AOD analysis developed (January 2012)\r
-//\r
-//\r
-//\r
-// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it (Nov. 2012):\r
-// - added new and removed other histograms \r
-// - Physics selection moved here (mainly for normalization in the efficiency calcuation)\r
-// - Centrality selection deleted\r
-// - 3DHisto denominator moved before any event selection for Normalization\r
-// - injected and natural part of MC selection removed\r
-// \r

+// AliAnalysisTaskCheckPerformanceCascadePbPb class
+// This task is for a performance study of cascade identification in PbPb.
+// It works with MC info and ESD/AOD.
+// Origin : AliAnalysisTaskCheckPerformanceCascade class by A. Maire Nov2010, antonin.maire@ires.in2p3.fr
+// Modified for PbPb analysis: M. Nicassio Feb2011, maria.nicassio@ba.infn.it:
+// - physics selection moved to the run.C macro
+// - added centrality selection and possibility to select events in nTracks ranges
+// - added new histograms
+// - modified binning of some histograms and containers
+// - flag to enable CF container usage
+// - check in the destructor for CAF usage
+// - flag for acceptance cut in the MC part
+// - in the MC particle selection IsPhysicalPrimary added and number of particles taken as appropriate for HIJING
+// (however for cascades one gets the same if runs on Nprimaries in the stack and does not check IsPhysicalPrimary)
+// - automatic settings for PID
+// - selection of injected cascades and HIJING cascades (kind of "bug" in method IsFromBGEvent())
+// - added proper time histograms for cascades and lambdas
+// - cos of PA V0 wrt Xi vertex and not primary vertex
+// - distance xi-V0 added in the container
+// - AOD analysis developed (January 2012)
+//
+//
+//
+// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it (Nov. 2012):
+// - added new and removed other histograms
+// - Physics selection moved here (mainly for normalization in the efficiency calcuation)
+// - Centrality selection deleted
+// - 3DHisto denominator moved before any event selection for Normalization
+// - injected and natural part of MC selection removed
+//
