Hello everyone, I've just started doing EXAFS in my research and I have found all your posts to be very helpful. My question is about the dk setting in Athena. I know from earlier reading that dk affects where the window for the FT is set in k-space (i.e. a dk setting of one moves the window out further than the k-min and k-max settings). I believe the purpose of this is to prevent cutting the tops of peaks out of the FT window. If this is the case, would a dk setting of 0 then be appropriate provided no parts of peaks are clipped as shown in a k-space plot with the window shown? Thanks, Geoff
