[yt-users] psf convolution

Does anyone know a way to convolve a yt image (preferably
pc.add_projection) with a telescope psf? This would be useful for
simulated observations. At the moment, the best I can do is make an
image in yt and then convolve that image in pixel space, but this ends
up blurring out things I do not want blurred (like particle markers, or
velocity arrows). The psf does not need to be fancy, I just want a 2D
gaussian with an adjustable width.
Ideally, there would be a call
pc.add_projection("Density", 0, psf_width = 1.5e13)
#create a projection with a psf width of 1 AU at the observed distance
