class AliTPC: public AliDetector

 Create Debug streamer to check simulation

 TPC destructor

 Add a hit to the list

 Create Materials for for TPC simulations

Generate table with noise

 get noise from table
  if ((fCurrentNoise%10)==0)
  fCurrentNoise= gRandom->Rndm()*fNoiseDepth;

 check if the sector is active

 activate interesting sectors

 activate sectors which were hitted by tracks
loop over tracks

 convert digits of the current event to raw data

 Converts the TPC raw data into summable digits
 The method is used for merging simulated and
 real data events

create digits from summable digits

 setting the defaults

 creates digits from hits

 Loop over all sectors for a single event

 TPC conversion from hits to digits.

 Single row digitization, coupling from the neighbouring
 rows taken into account

  Updates the list of tracks contributing to digits for a given row

 Initialise TPC detector after definition of geometry

 Reset number of digits and the digits array for this detector

 choice of the TPC side

 electron transport taking into account:
 1. diffusion,
 2.ExB at the wires
 3. nonisochronity

 xyz and index must be already transformed to system 1

 Create a new branch in the current Root Tree
 The branch of fHits is automatically split
 MI change 14.09.2000

Sets tree address for hits

 Set branch address for the TrackHits Tree

 add hit to the list

reset hits

 gets next hit

 Initialise the hit iterator
 Return the address of the first hit for track
 If track>=0 the track is read from disk
 while if track<0 the first hit of the current
 track is returned

Return the next hit for the current track

 remapping

return bool information - is track in given volume
load only part of the track information
return true if current track is in volume

  return kTRUE;
  if (fTrackHitsOld && fHitType&2) {
     TBranch * br = fLoader->TreeH()->GetBranch("fTrackHitsInfo");
     br->GetEvent(track);
     AliObjectArray * ar = fTrackHitsOld->fTrackHitsInfo;
     for (UInt_t j=0;j<ar->GetSize();j++){
       if (  ((AliTrackHitsInfo*)ar->At(j))->fVolumeID==id) return kTRUE;
     }
   }

Makes TPC loader

 load TPC paarmeters from a given file or create new if the object
 is not found there
 12/05/2003 This method should be moved to the AliTPCLoader
 and one has to decide where to store the TPC parameters
