[Ifeffit] Athena bug and a question

[Silvio Levy]

Bruce - thanks a lot for your post.  I've encountered this bug a few
times, but I thought it might be a problem with my machine; in any
case I could never replicate the problem and file a bug report.

I have another question to the list - how do I get rid of a spike at low k?  
See for instance http://www.msri.org/~levy/files/Cinnabar/cinnabar.prj

If you open this file with Athena and plot in k-space, there is a big
spike at low k; I haven't worried about this too much, but now that
I'm starting to show other people my work, I'd like to get rid of it.
Presumably my background subtraction is at fault, but how to fix it?
The spike also messes the normalization.

Thanks,

Silvio
