Class ElectronMatrixManager

class ElectronMatrixManager

derived from IMatrixManager

Used by tracksmearer to provide smear matrices corresponding to given track trajectories. It reads a flat file containing smear matrix data and creates a BinData object for every eta/phi bin.

private vector m_binData

vector of BinData objects, each corresponding to an eta/phi/pt bin.

private vector m_etaBins

bin boundaries

private string m_file1

name of flat file containing smear matrix data.

private string m_file2

name of flat file containing smear matrix data.

private int m_idconfig

detector configutartion

private vector m_momBins

bin boundaries

private int m_nbins

number of bins

private int m_option

matrix rescaling option

private HepRandomEngine * m_randomEngine

random number generator pointer

public ElectronMatrixManager()

Default Constructor

public ElectronMatrixManager(int option, HepRandomEngine * randomEngine)

Constructor taking matrix rescaling option and a random number generator.

public virtual ~ElectronMatrixManager()

Default Destructor

private const BinID getBinID(const TrackTrajectory & track)

returns BinID object corresponding to track trajectory

public const HepMatrix * getMatrix(const TrackTrajectory & track)

returns correlation matrix corresponding to given track trajectory

private void initialise()

reads file, creates BinData objects and asks them to calculate their matrices
