{}

void Clear(Option_t* opt = NULL)

Bool_t Build(AliTRDgeometry *const geo, Bool_t hlt = kFALSE)

 Init chamber and all time bins (AliTRDchamberTimeBin)
 Calculates radial position of the chamber based on
 radial positions of the time bins (calibration/alignment aware)

Int_t GetNClusters() const

 Basic loop method
 Returns number of clusters in chamber

void Bootstrap(const AliTRDReconstructor* rec)

 Basic loop method
 Bootstrap each time bin

void SetOwner()

 Basic loop method
 Set ownership in time bins

Double_t GetQuality()

 Calculate chamber quality for seeding.


 Parameters :
   layers : Array of propagation layers for this plane.

 Output :
   plane quality factor for seeding

 Detailed description

 The quality of the plane for seeding is higher if:
  1. the average timebin population is closer to an integer number
  2. the distribution of clusters/timebin is closer to a uniform distribution.
    - the slope of the first derivative of a parabolic fit is small or
    - the slope of a linear fit is small

Bool_t GetSeedingLayer(AliTRDchamberTimeBin*& layer, AliTRDgeometry *const geo, const AliTRDReconstructor* rec)

 Creates a seeding layer

void Print(Option_t* opt = NULL) const

 Print the chamber status

void Update()

 Steer purging of used and shared clusters
