[Ifeffit] Athena bug and a question

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
