ATHENA provides various kinds of data analysis. None of the data analysis capabilities in ATHENA require the use of FEFF. Analysis of data using FEFF is a huge topic and is thepurpose of the ARTEMIS program. The data analysis techniques included in ATHENA are all purely empirical. While there is no substitute for careful, sophisticated analysis of EXAFS data using theory from FEFF, often the empirical techniques described in this chapter are adequate to answer the questions you have about your data.
ATHENA's analysis tools are accessed from the Analysis menu, as shown below.
