Hi Joseph, The Fourier transform parameters for the background subtraction do not need to be the same for the analysis of chi(k). In fact, they really shouldn't be the same -- the goals for these FTs are very different., as the FT for background subtraction is only to determine a good background

Hi Joseph, I have a book chapter that explains how the different k-weighting affect the chi(k) data produced in the background removal. I'll send it to you directly, so as not to fill up everyone's mail box. Here is the reference for others that might be interested. Kelly, S.D., Hesterberg, D.
