Detailed Description

template<class T>
class casacore::KaiserBParam< T >

A one dimensional Kaiser-Bessel function.

Intended use:

Internal

Review Status

Test programs:
tFunctionHolder

Prerequisite

Etymology

A Kaiser-Bessel function

Synopsis

A Kaiser-Bessel is described by a height, a center, a width (halfwidth) and a parameter. The parameters are enumerated by HEIGHT, CENTER, WIDTH, KBPAR. They have default values of (1, 0, 1, 2.5).

Example

KaiserBFunction<Double> sf;
sf(0); // = 1.0
