			== Figure typo ==

			There is a typo in figure 3: "Application of PSF: Deconvolution of the mathematically modeled PSF and the low-resolution image enhances the resolution.". The asterisk is labeled "Devonvolution" when it should be "Deconvolution"

			== Airy Function equal to J1(x)/x? ==

			Can you either provide a reference for this statement:
			" In addition, a uniform function over a circular area (in one FT domain) corresponds to the Airy function, J1(x)/x in the other FT domain, where J1(x) is the first-order Bessel function of the first kind. "
			or correct it? Airy function is not quite what you say it is...

	I like the argument presented here: The FT of a uniformly illuminated circle creates an airy disc, therefor the FT of an airy disc is a uniformly illuminated circle. However, in this discussion there is the term: kr tan(Θmax), but I believe it should be kr sin(Θmax) to match what the FT of a circle aperature is. Is there a reference for the expression of kr tan(Θmax) used in this article?
