Detailed Description

template<class T>
class casacore::PoissonFunction< T >

A one dimensional Poisson function

Intended use:

Public interface

Review Status

Test programs:: tFunctionHolder

Prerequisite

Etymology

A 1-dimensional Poisson.

Synopsis

A Poisson is described by lambda. The parameters are enumerated by LAMBDA. They have default values of 1.

Example

PoissonFunction<Double> sf(5.0);

sf(25); // = 5.0
