[Ifeffit] [Question about XANES] Hello I'm a graduate student in Korea

Hello I'm a graduate student at POSTECH in Korea. Currently, I obtained XANES spectra over a narrow energy range and looked through the Athena manual But, I'm kind of lost as to how exactly I'm supposed to normalize raw data which only has XANES spectra. It would be very generous of you if you help me figure this out Thank you Best wishes Doyoub Kim
