Detailed Description
template<class T>
class casacore::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.
