Constructor & Destructor Documentation

JPDF::JPDF ( const std::string &  file_name, const double  TTS, const int  numberOfPoints = 25, const double  epsilon = 1.0e-10  )

inline

Constructor.

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

Parameters

file_name	file name
TTS	TTS [ns]
numberOfPoints	number of points for Gauss-Hermite integration of TTS
epsilon	precision for Gauss-Hermite integration of TTS

Definition at line 49 of file JPDF_t.hh.

Member Function Documentation

result_type JPDF::calculate ( const double  E, const double  R, const double  theta, const double  phi, const double  t1  ) const

inline

Get PDF.

The orientation of the PMT should be defined according this documentation.
In this, the zenith and azimuth angles are limited to

.

Parameters

E	muon energy at minimum distance of approach [GeV]
R	minimum distance of approach [m]
theta	PMT zenith angle [rad]
phi	PMT azimuth angle [rad]
t1	arrival time relative to Cherenkov hypothesis [ns]

Returns

hypothesis value
