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
