Constructor & Destructor Documentation

◆ JRegressorStorage() [1/2]

JFIT::JRegressorStorage< JPoint4E, JGandalf >::JRegressorStorage ( )

inline

Default constructor.

Definition at line 60 of file JShowerBrightPointRegressor.hh.

61 {}

◆ JRegressorStorage() [2/2]

JFIT::JRegressorStorage< JPoint4E, JGandalf >::JRegressorStorage	(	const std::string &	fileDescriptor,
		const double	TTS,
		const int	numberOfPoints = 25,
		const double	epsilon = 1.0e-10 )

inline

Parameterized constructor.

The PDF file descriptor should contain the wild card character JPHYSICS::WILDCARD which will be replaced by the corresponding PDF types listed in JRegressorStorage<JPoint4E, JGandalf>::pdf_t.

The TTS corresponds to the additional time smearing applied to the PDFs.

Parameters

fileDescriptor	PDF file descriptor
TTS	TTS [ns]
numberOfPoints	number of points for Gauss-Hermite integration of TTS
epsilon	precision for Gauss-Hermite integration of TTS
