Hi,
I want to create an array out of two sinc function.
My code looks like this right now:

;sinc psf
x=findgen(201)-100
psfx3=DBLARR(N_ELEMENTS(X))
for i=0, n_elements(x)-1 do begin
if x(i) eq 0 then begin
psfx3(i)=1
endif else begin
psfx3(i)=sin(x(i))/(x(i))
endelse
endfor
y=findgen(81)-40
psfy3=DBLARR(N_ELEMENTS(y))

for i=0, n_elements(y)-1 do begin
if y(i) eq 0 then begin
psfy3(i)=1
endif else begin
psfy3(i)=sin(y(i))/(y(i))
endelse
endfor
psf3=psfx3#psfy3
psf3=psf3/total(psf3)

plot,psfx3
stop
plot,psfy3
stop
shade_surf,psf3
end

The result is not what I am looking for.
I want something that looks like when raindrop hits water.
So when I do a contour plot it looks like elipsis.
How can I do this?

Thanks

PS: I use IDL 7.1. Not sure when IT will upgrade to 8.0
