Method Detail

setTopZ0Correction

public void setTopZ0Correction(double topZ0Correction)

Parameters:

topZ0Correction - Z0 correction to apply to top tracks.

setTopLambdaCorrection

public void setTopLambdaCorrection(double topLambdaCorrection)

Parameters:

topLambdaorrection - tan(lambda) correction to apply to top tracks.

setTopD0Correction

public void setTopD0Correction(double topD0Correction)

Parameters:

topD0Correction - D0 correction to apply to top tracks.

setTopPhiCorrection

public void setTopPhiCorrection(double topPhiCorrection)

Parameters:

setTopOmegaCorrection

public void setTopOmegaCorrection(double topOmegaCorrection)

Parameters:

topOmegaCorrection - 1/R correction to apply to top tracks.

setBotZ0Correction

public void setBotZ0Correction(double botZ0Correction)

Parameters:
