Hello,

Questions from a beginner in EXAFS...using Athena and Arthemis

>From where to get the error bars for number of neighbours, distance and sigsqr (ss)?

What are Chi-square,Reduced Chi-square and R-factor and how should be their values in a fit?

Sometimes it happen that  "R-factor for this data set" does not have the same value as the first R-factor from results. Why?

many thanks,

Elena
