Dear Bruce,

OK, I hear you.  I'll stop obsessing about the spike and only show 
chi*k^2 plots in my thesis :-)  

More seriously -- Your answer helps put things into perspective, and
the comparison between the FFT with k-range starting at 0 and 1 is
instructive.

It's worth noting, however, that in R space there is a hump from 
R=1 to R=1.4 that (to my knowledge) has no physical explanation, 
and which is more pronounced when the FT is taken starting at k=0.  
Should I not worry about this either?

Thanks

Silvio
