Many have noted over decades that Extended XAFS (EXAFS) and X-ray Absorption Near Edge Structure (XANES) studies have needed estimates of uncertainty and accuracy to solve structure, component analysis, and quantify the validity of alternate hypotheses. Many trying to address this, experimentally and from the data sets, have noted that this is ‘hard’. Usually, data collection uncertainties are neither measured nor propagated in X-ray Absorption Spectroscopy (XAS), whether in transmission or fluorescence mode. Here we summarise principles and recommendations for current and future investigations. We especially focus on repeated measurements, regular dark current measurements through an experiment, regular blank measurements through an experiment, multiple sample measurement, and measurements of particularly dominant systematics which might be time-dependent or energy-dependent.","PeriodicalId":20861,"journal":{"name":"Radiation Physics and Chemistry","volume":"16 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148717117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
