Data analysis

You may choose to use any data analysis package that you are familiar with. At the beamline we often use the IFEFFIT package for data reduction (Athena) and data analysis (Artemis). Further information and downloads (incl Athena, Artemis, and Hephaestus) can be found here: https://bruceravel.github.io/demeter/

A more recent (and potentially better!) alternative is Larch. Why not give it a go today and tell us what you think: https://millenia.cars.aps.anl.gov/xraylarch/

The beamline scientists are experienced in XAS data analysis and can provide some general advice in this regard. Please note, however, that it is not a specific task of the beamline scientists to analyse data for users and thus, should you wish to, please pursue their assistance in a reasonable manner.
