-// AliAnalysisTaskCheckCascadepp276 class
-//
-// Origin AliAnalysisTaskCheckCascade which has four roles :
-// 1. QAing the Cascades from ESD and AOD
-// Origin: AliAnalysisTaskESDCheckV0 by Boris Hippolyte Nov2007, hippolyt@in2p3.fr
-// 2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID)
-// 3. Supply an AliCFContainer meant to define the optimised topological selections
-// 4. Rough azimuthal correlation study (Eta, Phi)
-// Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr
-// Modified : A.Maire Mar2010
-//
-// Adapted to PbPb analysis: M. Nicassio, maria.nicassio@ba.infn.it
-// Feb-August2011
-// - Physics selection moved to the run.C macro
-// - Centrality selection added (+ setters) and histos
-// - flag and setters added (CF container usage, vertex range)
-// - histo added and histo/container binning changed
-// - protection in the destructor for CAF usage
-// - AliWarning disabled
-// - number of tracklets from AOD also
-// - automatic settings for PID
-// September2011
-// - proper time histos/container added (V0 and Cascades)
-// - cosine PA V0 wrt Xi vertex in the container
-// November2011
-// - re-run V0's and cascade's vertexers (SetCuts instead SetDefaultCuts!!)
-// - problems of libraries on Grid --> code copied in the task (from AliRoot v5-10-AN
-// where new pt dependent V0's cosPA cut implemented by Iouri)
-// - AOD analysis part completed
-//
-//
-// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it
-// Gen-now 2012
-// - Physics selection re-moved here (mainly for normalization in the efficiency calcuation)
-// - Centrality selection deleted
-// -

+// AliAnalysisTaskCheckCascadepp276 class\r
+//\r
+// Origin AliAnalysisTaskCheckCascade which has four roles :\r
+// 1. QAing the Cascades from ESD and AOD\r
+// Origin: AliAnalysisTaskESDCheckV0 by Boris Hippolyte Nov2007, hippolyt@in2p3.fr\r
+// 2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID)\r
+// 3. Supply an AliCFContainer meant to define the optimised topological selections\r
+// 4. Rough azimuthal correlation study (Eta, Phi)\r
+// Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr\r
+// Modified : A.Maire Mar2010 \r
+//\r
+// Adapted to PbPb analysis: M. Nicassio, maria.nicassio@ba.infn.it\r
+// Feb-August2011\r
+// - Physics selection moved to the run.C macro\r
+// - Centrality selection added (+ setters) and histos\r
+// - flag and setters added (CF container usage, vertex range)\r
+// - histo added and histo/container binning changed \r
+// - protection in the destructor for CAF usage \r
+// - AliWarning disabled\r
+// - number of tracklets from AOD also \r
+// - automatic settings for PID\r
+// September2011\r
+// - proper time histos/container added (V0 and Cascades)\r
+// - cosine PA V0 wrt Xi vertex in the container \r
+// November2011\r
+// - re-run V0's and cascade's vertexers (SetCuts instead SetDefaultCuts!!)\r
+// - problems of libraries on Grid --> code copied in the task (from AliRoot v5-10-AN\r
+// where new pt dependent V0's cosPA cut implemented by Iouri) \r
+// - AOD analysis part completed \r
+//\r
+//\r
+// Adapted to pp 2.76 analysis: D. Colella, domenico.colella@ba.infn.it\r
+// Gen-now 2012\r
+// - Physics selection re-moved here (mainly for normalization in the efficiency calcuation)\r
+// - Centrality selection deleted\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
-//

+// 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
