Bruce et al: 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. 2. in Chi(R) the window function seems to start dropping a bit further out than the set point. See the "r-space.png" attachment where the window point is at 1.009. Again it drops in a finite distance of about 0.02 in delta r. In the r-space case the drop is much more noticeable because the drop starts beyond the window set point. Hope this helps. Carlo On Thu, 31 Mar 2005, Scott Calvin wrote:
Here's a screenshot; this is the result after "Plot R" has been pressed. I'll try to whittle the project file down to the minimum necessary to generate the problem and then send it to you.

I suppose that I might be missing the point entirely, so I'll leave it with this: without a convincing screen shot demonstrating the problem, I am going to assume that there isn't one.
