Refering to this question again:

As I understand it now, the general approach is as follows:
-regress_polort DEGREE: generally the better approach to better preserve DOF. It also takes care of slow scanner drift impacts etc.
-regress_bandpass x y: might be required in certain cases, like in my case when computing the autocorrelation.
I am still interested in your opinion, especially if -regress_polort takes care of scanner noise etc. in frequencies below 0.01 Hz, so that -regress_bandpass is normally not required to exclude the former.
