Description Andrew Walker 2005-11-01 01:42:47 UTC

Version:           HEAD (using KDE KDE 3.4.0)
OS:                Linux

It would be useful if Kst could characterise a power spectrum in terms of 1/f, white noise, knee frequency, etc.

Comment 1 Netterfield 2006-02-15 01:51:55 UTC

Should be implemented as a fit plugin.

Comment 2 Andrew Walker 2006-05-02 23:10:49 UTC

This is now a requirement for LFI.

"It shall be possible to calculate the 1/f noise knee frequency and slope from an imput scientific data stream..."

Comment 6 Andrew Walker 2007-03-08 20:39:40 UTC

It would be good if this could be added prior to the upcoming release.

Comment 7 Andrew Walker 2007-03-29 20:17:02 UTC

Duncan, can you provide some info on the state of this bug report?

Comment 8 Duncan Hanson 2007-03-29 20:24:14 UTC

The plugin is finished, but we still need to verify that the plugin
produces the same results as LIFE for a given set of data (currently
waiting for news about getting IDL 6+ at UBC to do this).

Didn't we talk about this yesterday?

Duncan.

Unless we receive a complaint we'll assume that the plugin produces the same results as LIFE.
