Request for X, Y, XX, XY, YY gaussian FWHM-weighted moments

Description

As an update to my previous request for moments in the output catalog files, particularly for the difference images, I'd like to refine that request to be the X, Y, XX, XY, YY moments with a Gaussian-weighted region with sigma of the FWHM. I had some good discussions with Lupton over the weekend and he clarified that this was much more likely to be what I really wanted in the low noise regime.

what size Gaussian? function of seeing?

A Gaussian with the sigma of a characteristic FWHM for the image. Some aggregate value would be fine; it doesn't have to be too precise. No need to worry too much about variable PSF or ellipticity.
