Michael, If you use the same kmin for the standard and the unknown you will minimize the ambiguity. Anatoly - Reply message - From: "Michael Morrill" To: "ifeffit@millenia.cars.aps.anl.gov" Subject: [Ifeffit] S02 and k_min Date: Sun, Dec 2, 2012 1:02 PM H

Hello everyone, I am currently performing a simple curve fit on bulk MoS2 using an atoms file for crystalline MoS2. I've found that increasing k_min on my fit (e.g. from 2 to 4) improves the quality of the fit (R-factor from 0.028 to 0.009), but also increases S02. If I use a large enough k_min
