Re: [Ifeffit] The difference of EXAFS oscillation when using Athena and when using Larch

Hi Yuji, The attached larch script (a modification of your script but note: not python, so you may have to add a bunch of '_larch=mylarch' arguments) to show the effects of smoothing with Savitzky-Golay and of interpolating onto a "classic XAFS energy grid". You might want to play around with this different options. It definitely seems that none of these methods are systematically over-smoothing the data and reducing the amplitudes of the oscillations -- one more reason to use Larch instead of Ifeffit. But it also seems like smoothing this data with a Savitzky-Golay fitler is helpful. Also attached are plots showing k- and R-space generated from the attached script. --Matt
