Re: Bug in fourier_info ???

[0] I doubt fourier_info has a bug

[1] It is difficult to compare visually since NCL returns the
     phases as 0 to 360 while Matlab (apparently) uses -180 to 180.
     It would be better to match the same ranges.

[2] Suggestion: Use a 'circular' color map to color plot phases.
                 That way you do not get abrupt color changes
                 at the 'ends': eg 359->1 or -179 and 179

[3] Download the just released 6.2.0. It has few circular color tables
     that may be of use.
