Isn't the FFT of a gaussian another gaussian?
If you look it up in a book, you could compute
the PSF in the frequency domain. Could save some time.
It will be tricky because of the symetry about the origin.

As hinted at earlier, this could easily be overcome by defining
some x and y axis arrays.

So the PSF in FFT domain might look something like
psf = exp(c*((x*x+y*y)))
