Detailed Description

template<class T>
class casa::ExpSincConv< T >

Exponential times a Sinc.

Synopsis

An Exponential times a Sinc

The value(T &x) is given by Exp(-(abs(x) / expscale) ** exppow) * Sinc( pi * x / sincparm)

where the 3 paramaters correspond to those in the default constructor Note that the default case of exppow = 2 is a Gaussian times a Sinc. Since this is often a useful case, that parameter appears last in the constructor.
