Is there a method to verify poles and zeroes and an instrument correction?
I have posted a noise plot at http://mit.midco.net/rpratt   On the plot it
appears there are notches or steps that do not appear in a WinQuake FFT of
raw data.  I have tried to repeat with several data files and the results
are similar and that's why I question the instrument correction but the
plotting also includes smoothing that could be a factor.
