[yt-users] Power spectrum

[j s oishi]

Hi Miguel,

I'm working on adding a general fourier analysis toolbox to yt, but it
is not yet complete. For right now, the quickest way to do a power
spectrum using yt is to extract a covering grid (which
gives a cubic volume with constant resolution), and then use numpy's
FFT tools to convert to k space and average over shells in k space.

If you'd like to try the fourier analysis module in yt, you can get
the changesets from my dev fork of yt,

https://bitbucket.org/jsoishi/yt

I'd be happy to step you through it off-list, as it is not quite
finalized yet, and nice things like automatic k-space shell averaging
are not yet in there.

Please let me know if you have any further questions.

Jeff
