Carlo,
The screenshot did not come through to me but I can tell you what I have discovered for the Kaiser-Bessel function:
1. in Chi(k) the window starts to drop at the selected value. It reaches zero a bit lower (higher) than the value set. In k-space, it is hard to see this because of the scale but if you zoom, you can see that the drop takes about 0.05 delta k. See the "k-space.png" attachment where the window is set to 2.997.
It's probably that 0.05Ang^-1 is the spacing between points in k-space, so you're just seeing the line that join two successive points. The danger of looking too closely! --Matt
