class AliESDEvent: public AliVEvent

 Standard destructor

 funtion to reset using the already allocated space

 Reset the standard contents

 Add V0

 Check if a given detector was read-out in the analyzed event

 Print header information of the event

 Attaches the complementary info to the ESD

 Remove a kink candidate and references to it from ESD,
 if this candidate does not come from a reconstructed decay
 Not yet implemented...

 Remove a V0 candidate and references to it from ESD,
 if this candidate does not come from a reconstructed decay

 Remove a track and references to it from ESD,
 if this track does not come from a reconstructed decay

 Remove the data which are not needed for the physics analysis.

 1) Cleaning the V0 candidates

    If the cosine of the V0 pointing angle "csp" and
    the DCA between the daughter tracks "dca" does not satisfy
    the conditions

     csp > cleanPars[1] + dca/cleanPars[0]*(1.- cleanPars[1])

    an attempt to remove this V0 candidate from ESD is made.

    The V0 candidate gets removed if it does not belong to any
    recosntructed cascade decay

    12.11.2007, optimal values: cleanPars[0]=0.5, cleanPars[1]=0.999

 2) Cleaning the tracks

    If track's transverse parameter is larger than cleanPars[2]
                       OR
    track's longitudinal parameter is larger than cleanPars[3]
    an attempt to remove this track from ESD is made.

    The track gets removed if it does not come
    from a reconstructed decay

 Add a pileup primary vertex reconstructed with SPD

 Add a pileup primary vertex reconstructed with SPD

 Add track

 Add a new track

 move MUON clusters and pads to the new ESD structure in needed.
 to ensure backward compatibility

 get the MUON track at the position i in the internal array of track

 get the MUON+MFT track at the position i in the internal array of track

 add a MUON track

 add a MUON+MFT track

 create a new MUON track at the end of the internal array of track

 create a new MUON+MFT track at the end of the internal array of track

 get the number of MUON clusters

 get the MUON cluster at the position i in the internal array of cluster

 find the MUON cluster with this Id in the internal array of cluster

 create a new MUON cluster at the end of the internal array of cluster

 get the number of MUON pads

 get the MUON pad at the position i in the internal array of pad

 find the MUON pad with this Id in the internal array of pad

 create a new MUON pad at the end of the internal array of pad

 Add kink

 Add calocluster

 use already allocated space

 Set the TPC vertex
 use already allocated space

 Set the SPD vertex
 use already allocated space

 Set the primary vertex reconstructed using he ESD tracks.
 use already allocated space

 Get the "best" available reconstructed primary vertex.

 Removes diamond constraint from fPrimaryVertex (reconstructed with tracks)
 Returns a AliESDVertex which has to be deleted by the user

 Set the SPD Multiplicity

 use already allocated space

 use already allocated space

 Extracts the complementary info from the ESD

 Add an object to the list of object.
 Please be aware that in order to increase performance you should
 refrain from using TObjArrays (if possible). Use TClonesArrays, instead.

 set pointers for standard content
 get by name much safer and not a big overhead since not called very often

 Set the names of the standard contents

 create the standard AOD content and set pointers

 Create missing standard objects and add them to the TList of objects

 Add cosmic tracks for cases where esd files were created
 before adding them to the std content

 Find object with name "name" in the list of branches

 fills the provided TRefArray with all found phos clusters

 fills the provided TRefArray with all found emcal clusters

 Book the branches as in TTree::Branch(TCollection*)
 but add a "." at the end of top level branches which are
 not a TClonesArray

 Connect the ESDEvent to a tree

 Method which copies over everthing from the old esd structure to the
 new

 Check if the event satisfies the trigger
 selection expression trigExpr.
 trigExpr can be any logical expression
 of the trigger classes defined in AliESDRun
 In case of wrong syntax return kTRUE.
 Modified by rl for 100 classes - to be tested

 get the HLT trigger decission object

 get the HLT trigger decission description

 get the HLT trigger decission description

 This function checks if there was a pile up
 reconstructed with SPD

 calculates 3 estimators for the multiplicity in the -eta:eta range
 tracklets   : using SPD tracklets only
 trITSTPC    : using TPC/ITS + complementary ITS SA tracks + tracklets from clusters not used by tracks
 trITSSApure : using ITS standalone tracks + tracklets from clusters not used by tracks
 if useDCAFlag is true: account for the ESDtrack flag marking the tracks with large DCA
 if useV0Flag  is true: account for the ESDtrack flag marking conversion and K0's V0s

 Set the TOF event_time

 Get VZERO Multiplicity for channel i
 Themethod uses the equalization factors
 stored in the ESD-run object in order to
 get equal multiplicities within a VZERO rins (1/8 of VZERO)

 Reset TClonesArray of TOF clusters

 Reset TClonesArray of TOF clusters

 Connect tracks to this event
