GAUSS_SMOOTH

GAUSS_SMOOTH
This task performs a 2-D smoothing by an elliptical gaussian. The al-
gorithm works in the Fourier plane and the first 2 dimensions (in
pixels) should therefore be powers of two (but need not be equal). It
is much faster than the equivalent sky plane algorithm, but you should
beware of aliasing effects when the size of the convolving gaussian
becomes a sizeable fraction of the map (say 30%).
