Detailed Description

A GausDesc describes a Gaussian distribution.

Two are used by GaussianDiffusion. One describes the transverse dimension along the direction of wire pitch (and for a given wire plane) and one the longitudinal dimension is along the drift direction as measured in time.

Member Function Documentation

binint()

std::vector< double > Gen::GausDesc::binint	(	double	start,
		double	step,
		int	nbins
	)		const

Integrate Gaussian across uniform bins. Result is normalized assuming integral of Gaussian over entire domain is 1.0.

distance()

double WireCell::Gen::GausDesc::distance ( double  x )

inline

Return the distance in number of sigma that x is from the center.

sample()

std::vector< double > Gen::GausDesc::sample	(	double	start,
		double	step,
		int	nsamples
	)		const

Sample the Gaussian at points on a uniform linear grid.

weight()

std::vector< double > Gen::GausDesc::weight	(	double	start,

		int	nbins,
		std::vector< double >	pvec
	)		const

Integrate Gaussian diffusion with linear weighting to redistribute the charge to the two neartest impact positions for linear interpolation of the field response
