Connes

The apodization function

A(x)=(1-(x^2)/(a^2))^2.

Its full width at half maximum is sqrt(4-2sqrt(2))a.

Its instrument function is

I(k)=8asqrt(2pi)(J_(5/2)(2pika))/((2pika)^(5/2)),

where J_n(z) is a Bessel function of the first kind. This has a maximum of 16a/15, and full width at half maximum of 1.90416/L.
