For sample mass calculation in planning for your beamtime experiment, following programs are helpful:

• CatMass by Jorge Perez-Aguilar & Adam Hoffman (last update: 11-16-2022) 
• "Formulas" menu in Hephaestus 
• XAFSmass calculator 

For the X-ray absorption spectroscopy (XAS) data processing and analysis, we use DEMETER Package, which includes:

• Athena, a program for XAS data processing
• Artemis, a program for EXAFS data analysis 
• Hephaestus, a collection of beamline utilities based on tables of atomic absorption data
