get ClusInfObj from category using index

 calculates the bin of the the level parameter
 access the corrections

 calculate the the bin of the angle (option=0 ... theta; =1 ... phi)

 Convert MDC's phi angle to the coordinate system used
 in other detectors.  input mdc phi in rad and sector
 coordinate system => output in deg and hades coordinate system

 Convert MDC's theta angle to the coordinate system
 used in other detectors

 return the HGenatKine object pointer
 for a given track number. returns NULL
 if something wrong

this calculated CommonGeantTrack in a way I consider it is correct
return positive value for  e+ e- common track and:
      -2 ring-pi
      -3 ring-p
      -5 ring-another lepton
      -4 ring-mdc corr ele-meta not
      -1 ring-non sence in meta
      -10 richhit is null pointer

 returns kTRUE if kine is a lepton
 originating from gama->e- gama

 returns kTRUE if kine is a lepton
 originating from pi0 ->gama->e+e-

 returns kTRUE if kine is a lepton
 originating from gama->e+e-

 returns kTRUE if kine is a lepton
 originating from pi0

 returns kTRUE if kine is a lepton
 originating from eta dalitz

 returns kTRUE if kine is a lepton

 The method operates only on simulation data.
 Using the geant track numbers of the tracks
 in mdcseg (5 tracks stored) decide whether
 it is a single tracks from lepton or not
 Check also whether it is inner segment. If not
 returns false.
 look only at inner segments :very important

 returns kTRUE if hit has only one track
 conribution and is a lepton

this method have following return values
 0 ... normal single
 1 ... normal double
 2 ... double => because possition of pair
                 lepton to track in MdcGeant too
                 close to MdcHit possition
-1 ... nothing of previous
 return value 2 was introduced because the lack of
 complete propagation  of all contributing track numbers
 from contributing wires to segment for fitted one.
 This is in version v6_11

 The method operates only on simulated data.
 Using the geant track numbers of the tracks in
 mdcseg (5 tracks stored) decide whether
 it is a double tracks from lepton or not
 conv_more =0 seg is DOUBLE if there are
            2 different leptons contributing to it
 conv_more =1 seg is DOUBLE if there are 2 different
            leptons contributing to it and leptons
 are conversion pair

 The method operates only on simulated data.
 Using the geant track numbers of the tracks in mdcseg
 (5 tracks stored) decide whether it is a double tracks
 from lepton or not conv_more =0 seg is DOUBLE if there
 are 2 different leptons contributing to it and they are pair
 conv_more =1 seg is DOUBLE if there are 2 different leptons
 contributing to it and leptons are conversion pair. Update
 from v6_12 for complete list of track num related to hit
 one has to look at MdcClusInf

 this method look if mdcseg that corresponds to
 geant tracknumber track if found at the same place in GeantMdc

this method finds a pair lepton to lepton with track1
I use the fact that it is either track1+1 or track1+1

this method finds a pair lepton to lepton with track1
I use the fact that it is either track1+1 or track1+1

input 2 kine objects
output opening angle of trajectories

copy from HPidFL

filling the array arr

checking if number cls is already in arr

put all entries to -1

check whether track tr is in GeantMdc inner modules

check whether track tr is in GeantMdc inner modules

check whether track tr is in GeantTof

check whether track tr is in GeantShower

look whether this track is seen in rich-mdc tof||show

checking wheather both PidParticles fullfill CPR propabilities to be single

 checking wheather HPidParticle pass a probability to be a single
 mode_rs =0 for simulation data
 mode_rs =1 for real data

this check common hits of leptons in pairs
return values:
0 : no common hits
1 : R-  common RICH hit
2 : M-  common MDC hit
3 : RM- common RICH and MDC hits
4 : Me- common META hit
5 : RMe-common RICH and META hits
6 : MMe-common MDC and META hits
7 : should not happend
-1: default return
