I have some data that I know is the convolution of a sinc function (fourier transform artifact) and a gaussian (from the underlying model). I would like to fit this data to a functional form of the convolution - is there an analytic form of the convolution of a sinc and a gaussian?

    The convolution of a sinc and a gaussian is the Fourier transform of the _product_ of a rect and a gaussian which is a truncated gaussian. Maybe looking at the problem in the transform domain might be useful.2012-01-11
